A homogeneous and uniform rod of length 10ft and weight 100lbs rests in the corner of a room as shown. The coefficient of static friction between the rod and floor is (Us=.4). There is no friction between the rod and the wall although there is a compression force. What is the minimum angle that the rod can make with the floor and still be in equilibrium?© BrainMass Inc. brainmass.com March 4, 2021, 6:05 pm ad1c9bdddf
See the attached file for the diagram.
The 4 forces on the rod are its weight m*g (downward -- at its center of mass halfway along the rod ), the normal force of the wall N1 (horizontal -- away from wall), the normal force of the floor N2 ...
The solution provides step-by-step calculations and explanations for finding the minimum angle between two objects. A diagram is also included as an attachment.
