Chapter 12, Problem 1P

(a)

To determine

Whether the given statement is true or false.

(a)

Expert Solution

Answer to Problem 1P

False.

Explanation of Solution

If an object is to be in equilibrium, the net force as well as net torque about any point must be zero. It is not sufficient that only net force is zero.

Conclusion:

Thus, the given statement is false.

(b)

To determine

Whether the given statement is true or false.

(b)

Expert Solution

Answer to Problem 1P

True

Explanation of Solution

If an object is to be in equilibrium, the net force as well as net torque about any point must be zero. It is not sufficient that only net force is zero but it is necessary that it is zero.

Conclusion:

The given statement is true.

(c)

To determine

Whether the given statement is true or false.

(c)

Expert Solution

Answer to Problem 1P

True

Explanation of Solution

If an object is to be in equilibrium, the net force as well as net torque about any point must be zero. This means ∑τ→=0 .

Conclusion:

(d)

To determine

Whether the given statement is true or false.

(d)

Expert Solution

Answer to Problem 1P

False

Explanation of Solution

If an object is to be in equilibrium, the net force as well as net torque about any point must be zero.

This does not mean that the object is at rest. It could be at rest or moving with constant velocity or rotating with constant angular speed.

Conclusion:

The given statement is false.
