Question

In the figure, forces A?, B?, C?, and D?, each have magnitude 55.0N and act at the same point on the object. Assume that x = 16.5cm .(Figure 1)

Part A

What torque (magnitude and direction) does A? force exert on the object about point P?

Let counterclockwise torques be positive, clockwise torques be negative.

Part B

What torque (magnitude and direction) does B? force exert on the object about point P?

Let counterclockwise torques be positive, clockwise torques be negative.

Part C

What torque (magnitude and direction) does C? force exert on the object about point P ?

Let counterclockwise torques be positive, clockwise torques be negative.

Part D

What torque (magnitude and direction) does D? force exert on the object about point P ?

Let counterclockwise torques be positive, clockwise torques be negative.

Part E

What is the total torque about point P ?

Let counterclockwise torques be positive, clockwise torques be negative.

Explanation / Answer

A)

torque of A = 55 * 0.165 * sin(60)

torque of A = 7.86 N.m

B)

torque of B = 55 * 0.165 * sin(0)

torque of B = 0 N.m

C)

torque of C = -55 * 0.165 * sin(30)

torque of C = -4.54 N.m

D)

torque of D = -55 * 0.165 * sin(90)

torque of D = -9.07 N.m
