A car engine with weight w hangs from a chain that is linked at ring 0 to two other chains, one fastened to the ceiling and the other to the wall. Find the tension in each of the three chains, assuming that w is the given weight and the rings and chains have no signicant weight. ILJI A toboggan loaded with children slides down a snow covered slope. The combined mass of the children and toboggan is 100kg. The angle (1 ofthe hill is 30 . What is the acceleration of the toboggan? A ball of mass m1=20kg and a block of mass m2 50kg are attached by a lightweight cord that passes over a frictionless pulley of negligible mass. The block lies on a frictionless incline of angle 30 . Find the magnitude of the acceleration of the two objects and the tension in the cord. \"*1 25. The sign for Pierre's restaurant has a mass of 82 kg. It is held out from the wall by a light horizontal steel rod, which supports no weight, and a wire at 40" to the horizontal, as illustrated. Find the tension in the wire and the compression in the steel rod
