(1) A rod of length L has a small square cross section b²; the density of the material is p. Just by intuition you know that the center of mass of this rod is "in the middle", at L/2; i.e. this is where you would support the rod to balance it on your finger. a. Calculate the total mass of this rod; and calculate the mass of a tiny bit of the rod, of length AL and cross-section b². b. Show (i.e. prove) that the center of mass is at L/2 by starting with the definition of the center of mass position for a continuous object.

1. You are a mechanical engineer at one of the oil and gas company and you face this technical problem inside plant: a broken chain issue that frequently occured on a machine lately. Obviously this issue causes production activity stopped temporarily and production loss.This broken chain issue occured since about three months ago after we replaced the electric motor into the bigger one, it's about 2.2 KW or 3 hp. As an engineer in this department, You responsible to stop this broken chain happened on and on. So, make a calculation to find out the optimum specification of chain sprocket thru theoritical approach based on Machine Design. Motor Power (P) = 3HP 2.2 KW = 2337 Nm/s ni = 952 Rpm : speed of rotation od smaller spracket in rpm n2 = 600 Rpm : speed of rotation od larger spracket in rpm N1 = 17: Number of teeth on the smaller sprocket N2 = 27 : Number of teeth on the larger sprocket D1 = 44 mm : Ptich circle diameter of the small sprocket D2 = 74 mm : Ptich circle diameter of the…
