A heavy ball with a weight of 130 N is hung from the ceiling of a lecture hall on a 4.7-m-long rope. The ball is pulled to one side and released to swing as a pendulum, reaching a speed of 5.8 m/s as it passes through the lowest point. What is the tension in the rope at that point?

What is the major difference between thermoplastics and thermosetting plastics from the polymerization structure point of view?

Steel balls 12 mm in diameter are annealed by heating to 1150 k and then slowly cooled to 400 k in an air att 325 k and h -20 w/m2 k. assume the properties of the steel to be k- 40 w/m k,p 7800 kg/m3, and cp 600 j/kg k. a. determine whether lumped system method can be used to analyze this problem and if so why" b. determine the time required for the cooling process. c. determine the total amount of heat lost from each ball to the ambient air
