In The Figure (Figure 1) , What Is The Net Torque About The Axle

Given Data

Find the net torque about the axle. So, the net torque about the axle in clockwise direction is 1N⋅m 1 N ⋅ m .

What is the net torque about the center of mass?, About center of mass both forces produce the torque in the same sense that is anticlockwise. Thus, the net torque is non-zero and the body is only in translation equilibrium.

Furthermore, What is Torque in center of mass?, Torque is the rotational equivalence of force. So, a net torque will cause an object to rotate with an angular acceleration. Because all rotational motions have an axis of rotation, a torque must be defined about a rotational axis. A torque is a force applied to a point on an object about the axis of rotation.

Finally,  Why torque about Centre of mass is zero?, In the diagram shown, a force is applied at the center of the rod. Because of this force, the rod translates and the center of mass of rod accelerates, but the rod does not rotate and remains in rotational equilibrium. In this case, the torque about the center of mass is zero.

Frequently Asked Question:

How do you calculate net torque?

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 the net torque?

Net torque means calculating the resulting torque from ​n​ different contributing forces.

How do we calculate 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.

How do you find net torque with two forces?

Since the weight is the only force exerting a torque on the rod, then τnet = τMg = -Mg(L/2)cosθ. We can now solve for the angular acceleration.

Does center of mass affect torque?

The rotation of a body depends upon the point at which it is hinged. So if a force applied at the center of mass (COM) then it may cause rotation about the axis (if it’s not the one through COM) at which it is hinged by causing a torque to act. … A torque still acts about the axes other than that of the COM.

Why is torque zero at center of gravity?

Since the normal force by the hook works in the rotation point, this gives no torque (the distance r is zero). Therefore only gravity is left to do a torque to make it rotate. And if the CoM is vertically below the rotation point, then also gravity gives no torque as explained above.

Why is center of mass zero?

9-14 tells us that 0 also. Because acceleration is the rate of change of velocity,we conclude that the velocity of the center of mass of the system of two balls does not change. … Such forces do not contribute to the net force ,which remains zero.

What is the torque on an object about its Centre of gravity?

TorqueCenter of gravity. about an axis is called torque or moment of force.” Positive torque: If a body rotates about its axis in anti clockwise direction, then the torque is taken positive .
