Question # 5: (6 Marks) The pendulum consists of a 6-kg circular plate, 5 kg rectangular plate and a 4-kg slender rod. Locate the mass center of the pendulum () and determine the radius of gyration (k) of it about an axis perpendicular to the page and passing through point o. 2 m le 0.5 m Ti 1.5 m
Question # 6: (6 Marks) The uniform 20 kg slender bar AC rotates in a vertical plane about the pin at B. The spring AD has a spring constant k = 15 N/m and an undeformed (unstretched) length Lo = 2 m. The bar is initially at rest in the position 8 = 0' (vertical). It is then released from this position. Due to gravity, the bar AC starts to rotate clockwise. Find the angular velocity of the bar when 8 = 90° horizontal) using principle of work and energy 120-kg- 4 m 3 m B 2 m
