Several students visit a playground and one of them pushes the others on a merry-go-round.The diameter of the merry-go-round is 3.0 m, and the...

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.
