A cross bar wrench is used to tighten a nut as shown in the figure. The torque exerted by the wrench is
Correct answer: B. 40Nm
- A. 80 Nm
- B. 40Nm
- C. 20 Nm
- D. 10 Nm
Explanation
The forces are acted at a distance of 0.2m from the center, the torques is given by 2(100*0.2) = 40 NM. The forces are in anticlockwise direction both, so they are added up while calculating torque.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
