Unformatted text preview: verge of slipping. Determine the coefcient of friction between the friction pad at A and the ground if the inclination of the ladder is = 60 o and the wall at B is smooth. The center of gravity for the man is at G . Neglect the weight of the ladder. Problem 6 If the center of gravity of the stacked tables is at G , and the stack weighs 100 lb, deter-mine the smallest force P the boy must push on the stack in order to cause movement. The coefcient of static friction at A and B is s = 0.3. The tables are locked together. Problem 7 Wear your E14 T-shirt and take a landscape format photo of yourself in a funny situa-tion. The photo must contain either a shear and moment diagram situation (chapter 7) or a friction problem (chapter 8). Upload your photo through your coursework drop box. The ve most creative photos will receive ve extra bonus points . 3...
