-100 Question 3 (10 points): The slender rod is subjected to a couple moment M and a constant horizontal force P. What is the work done by the force P when the rod swing from its vertical position (0 = 0) to the current position (0 = 30") shown? A) 0.5 PI B) -0.5 PI C) 0.87 PL D) -0,87 PI E) Other P Question 4 (10 points): The cylinder A of radius R has a mass m and the radius of gyration kg = R/2 and rolls without slipping on the horizontal surface. The block B has a mass m. What is the ratio of the kinetic energy of the cylinder Tx and the kinetic energy of the block Tu? A) TT3 = 3 B) T/T, = 4 C) T/T = 5 D) T/T, = 6 E) Other Question 5 (10 points): The bar has a mass m and length L. The spring attached to its end always remains vertical due to the roller guide, and it is unstretched when 0 = 30 The datum for gravitational potential energy is at position 8 -0°. What is the system's potential energy at position 8 = 90°? 2 A) B) D) E) Other 7 mol MOL 2 mat 8
