Question: what is the magnitude of net torque about the axle? Express your answer to two sign?

Part A

In the figure (Figure 1) , what is the magnitude of net torque about the axle?

Express your answer to two significant figures and include the appropriate units.

Part B

What is the direction of net torque about the axle?

Counterclockwise?

Clockwise?

the magnitude of the net torque
the magnitude of the net torque

Answer:

0.2Nm

Clockwise

r=0.02 m

Torque = r*30-r*20 ( taking inside the plane +ve direction)

Thus you get the answer 0.2 which is positive hence net torque in clock wise direction.

What is the magnitude of the net torque on the pulley about the axle?

Answer:

Torque= tangential force × radius of the pulley

Pulley is a simple machine which helps us to lift loads by applying the force in a convenient direction. It consists of a grooved wheel which is free to rotate about an axle passing through the center of the pulley.

For a pulley, the torque  tangential force × radius of the pulley

Pulleys can be used in combination also to achieve a desired output.

what is the magnitude of the net torque about the axle?

 In what magnitude force provides 4.0 N m net torque about the axle? Express your answer with the appropriate units

Torque is expressed as:

τ=rFsinθ, where r is the lever arm, F is the force applied, and θ is the angle between r and F.

Looking at the diagram, the angle between r and -F is zero. That is, r and -F are parallel. Thus, the torque due to (-F) will be zero since sin0 = 0.

The angle between r and F is 90°. Thus, the positive force generates torque.

What is the net torque about?

The net torque is the sum of the individual torques.

Rotational Equilibrium is analogous to translational equilibrium, where the sum of the forces are equal to zero.

How is net torque calculated?

The individual torques add to produce a net torque about the axis. When the appropriate sign (positive or negative) is assigned to the magnitudes of individual torques about a specified axis, the net torque about the axis is the sum of the individual torques: →τnet=∑i|→τi|.

What is net force and net torque?

Its associated torque, the net force, becomes the resultant force and has the same effect on the rotational motion of the object as all actual forces taken together. … It is possible for a system of forces to define a torque-free resultant force.

What is torque in physics class 9?

Torque is the measure of the force that can cause an object to rotate about an axis. … The point where the object rotates is called the axis of rotation. In physics, torque is simply the tendency of a force to turn or twist.

What is Net Force formula?

Formula of Net ForceWhen the body is at rest, the net force formula is given by, FNet = Fa + Fg. … When a force is applied to the body, not only is the applied force acting, there are many other forces like gravitational force Fg, frictional force Ff and the normal force that balances the other force.

How do you calculate total torque?

A practical way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force. and the magnitude of the torque is τ = N m.

What are the units of torque?

Torque/SI units
Unit of torque: newton metre (N m) The quantity torque (or moment of force) may be thought of as the cross product of force and distance and the SI unit for torque is Newton metre, N m (m2 kg s-2).Apr 3, 2020

What does no net torque mean?

A torque is a vector quantity which means that it has both a magnitude (size) and a direction associated with it. If the size and direction of the torques acting on an object are exactly balanced, then there is no net torque acting on the object and the object is said to be in equilibrium.

What is net force in physics class 8?

The net force is the force which is the sum of all the forces acting on an object simultaneously. Net force can accelerate a mass. Some of the other forces act on anybody either at rest or motion. The net force is a term used in a system with multiple forces.

Does net force include torque?

Since torque is always about some point, if there’s a net force on an object you can always find some point about which there will be a torque. But you can certainly have a net force on an object that gives no torque about its center of mass.

What is a torque in physics?

torque, also called moment of a force, in physics, the tendency of a force to rotate the body to which it is applied.

What is torque simple?

In simple terms, the definition of torque is the engine’s rotational force. … Specifically, torque actually measures the amount of force required to twist an object (for example when tightening the lid on a fizzy pop bottle, a wheel-nut or cylinder head bolt).

What is torque Engineering?

In US mechanical engineering, torque is defined mathematically as the rate of change of angular momentum of an object (in physics it is called “net torque”). … For example, a rotational force applied to a shaft causing acceleration, such as a drill bit accelerating from rest, results in a moment called a torque.

How do you write net force?

Net Force Equation Can Be Stated As Follows

Fg = Gravitational force. Net force is when a body is in motion and many forces are active on it like gravitational force Fg, frictional force Ff, and the normal force. FNet = Fa + Fg + Ff + FN.

How do you calculate power torque?

  1. Torque (lb.in) = 63,025 x Power (HP) / Speed (RPM)
  2. Power (HP) = Torque (lb.in) x Speed (RPM) / 63,025.
  3. Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)
  4. Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488.

How do you find the net torque of an origin?

Take the cross product of →rand→F r → and F → to determine if the torque is positive or negative about the pivot point or axis. Evaluate the magnitude of the torque using r⊥F r ⊥ F . Assign the appropriate sign, positive or negative, to the magnitude. Sum the torques to find the net torque.

what is the magnitude of the net torque about the axle?

What is 1 Nm of torque?

One newton-metre is the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm that is one metre long. The newton-metre (also newton metre or newton meter; symbol N⋅m or N m) is a unit of torque (also called moment) in the SI system.

What is torque and How Is It measured?

Torque is measured in pounds-feet, meaning a force in pounds acting on the end of a lever measured in feet. For example, if that lug wrench is 2 feet (0.6 m) long, and you put 100 pounds (45.4 kg) of force on it, you are putting 200 pounds-feet (27.65 kg/m) of torque onto the bolt.

Why is torque important?

Torque is a crucial part of generating power from a car’s engine, as it represents the load an engine can handle to generate a certain amount of power to rotate the engine on its axis. … Multiply this torque force (in lb-ft.) by the axis’s rotational speed per minute (RPM) and you get the engine’s power output.

What is net external torque?

Torque can be defined as the rate of change of angular momentum, analogous to force. The net external torque on any system is always equal to the total torque on the system; in other words, the sum of all internal torques of any system is always 0 (this is the rotational analogue of Newton’s Third Law).

Why is the net torque equal to zero?

If an object is in motion at a constant speed and constant direction, and/or is rotating at a constant rate, then that means there is no linear or angular acceleration which implies that the net force and net torque are equal to zero–which implies equilibrium.

What is net force Class 10?

A net force is defined as the sum of all the forces acting on an object. … For example in free fall, the net force on an object equals its weight – the one force pulling on it.

What is net force in science?

The net force is the combined effect (the sum) of the real forces acting on the object. … The magnitude of the net force on the object is the product of its mass and its acceleration (Newton’s second law of motion).
