The torque applied by the student is given as T = F * r * sin A, where F is the force, r is the radius vector and A is the angle between the radius vector and the force vector.

- The torque applied by the student is 50*3* sin 110

=> 140.95 N.m

- To achieve maximum torque the student would have to apply the force in a direction that forms an angle of 90 degrees with the direction of the radius vector.

- If the force applied by the student is 50 N, he can increase the torque to a maximum of 50*3*sin 90 = 150 N.m by changing the direction at which the torque is being applied.
