Assignment:
Question 1. A 1200 N uniform boom is supported by a cable; one end of the cable being attached to a wall and the other end to top of the boom. The cable is perpendicular to the boom. One end of the boom is attached to a hing on the ground and is leaning away from the wall at an angle of 65 degrees to the ground. A 2000 N weight hangs from its top. Find the tension in the supporting cable and the components of the reaction force exerted on the boom by the hinge.
Question 2. A 240 N sphere, 0.20 m in radius rolls without slipping 6.0 m down a ramp that is inclined at 37 degrees with the horizontal. What is the angular speed of the sphere at the bottom of the slope if it starts from rest?
