2.) A person uses a force P to keep the pulley system in equilibrium. The mass shown is 10 kg. Note that there are 2 ropes. The first is from the center of the large pulley down to the mass. The 2d rope starts from the center of the large pulley, travels up through the other 2 pulleys and is held in place by force P. All sections of rope shown between pulleys are vertical. EXTERNAL FORCES a.) Draw the FBD of the entire pulley-mechanism. Label external forces. b.) Draw the FBD of each pulley and solve for force P. c.) Solve for the external reaction forces for the mechanism at A, B. B P

Transcribed Image Text:2.) A person uses a force P to keep the pulley system in equilibrium. The mass shown is
10 kg. Note that there are 2 ropes. The first is from the center of the large pulley
down to the mass. The 2nd rope starts from the center of the large pulley, travels up
through the other 2 pulleys and is held in place by force P.
All sections of rope shown between pulleys are vertical.
