Question

A rigid beam of mass 7.12 kilograms and length 1.57 meters is fixed at point P, around which the beam can rotate.

 

a. What is the torque on the beam caused by only gravity? Include units in your answer. 


 
b. If there is no force F2, what force F1 is required to put the beam in rotational equilibrium? Include units in your answer. 

 
c. If force F1 is only 20 newtons, what force F2 exerted 0.35 meters from point P and acting at an angle of 45.7 degrees is required to put the beam in rotational equilibrium? Include units in your answer.
