SEMESTER COURSECODE. : MP104 SPRING 2008 10 TH .WEEK MIDTERM GROUP : 1 TIME ALLOWED : 90 MIN. NAME: PR.NO. : SEC: GROUP: SOLUTION ANSWER THE FOLLOWING QUESTIONS : 1. A 10-kg block (C) moves along a smooth inclined plane and is subjected to a compressing variable force P . The block (C) is attached to a rope which connects another ( 20 – kg) block (E) and passes along a smooth fixed pulley (D) , while the block (E) is attached by a rope to a motor (H) through a fixed pulley at (F). The block (C) starts from point A. where x A = 20 m , to move upwards with initial velocity v A = 45 m / s . If the acceleration of the block (E) is varying according to the relation : a = 6( t - 4 ) m / s 2 , and the motor torque is (M = 32 N .m) and the system is designed to move only for 4 seconds , determine the force P as a function of the...
