Question 7: Albert Einstein is standing on the left end of an 8.00-m long, 20.0-kg rod.  The right end of the rod is attached to the outside of wall of a building.  A cable is attached to the rod 2.00 m away from Albert at an angle of 25° from horizontal. Albert Einstein’s weight is 600 N. a) Draw a rigid body FBD for the rod. b) In what vertical direction does the wall push on the rod? Explain and use calculations to support your answer. c) What is the size of the vertical force that the wall exerts on the rod?
