What is the clockwise torque on the following lever? 5.0 nm 125 nm 250 nm 0.0 nm

The correct answer is B:  125 Nm

Explanation:

If an applied force causes rotation from upward to downward direction than the torque is clockwise and is called as negative clockwise torque. Minus sign represents the direction of the torque. SI unit of torque is Nm.

Given data:  

Force = 25 N

r = 5.0 m

Formula:

Torque = r x F

          = 5.0 m X 25 N

          = 125 Nm  

The clockwise torque is 125 Nm ( i.e -125 Nm. Here minus sign suggests that the torque is clockwise)

the answer is c. nacl
