Drop-load (II) Context We want to lower a suspended load in a controlled way so that it hits the ground with a speed whose modulus is not too great. To do this, the suspended load (B) is connected by a rope passing through a pulley to another mass (A), which can move on a horizontal surface. A spring is attached to mass A to slow down the motion. Information The masses of the charges A and B are known.The pulley is a ring (a hollow cylinder) of mass mp and radius R that can rotate without friction.The surface on which mass A is placed is horizontal.There is friction between mass A and the surface it sits on, the coefficient of friction is uc.The string attached to mass A is perfectly parallel to the surface on which the mass rests.The spring is horizontal, initially unstretched and its spring constant is known. Modelization Create a model for the modulus of the velocity of mass B when it hits the ground, given the known parameters of the problem that are relevant. Mass of charge A : 75…

Assuming nm =80% and an indicated mean effective pressure of 9.5 bar, determine the required bore and stroke. If the compression ratio of the engine is to be 7.5 to 1, determine consumption of petrol in kg/h and in kg/bp.hr. Take the ratio of the indicated thermal efficiency of the engine to that of the constant volume air standard cycle as 0.65 and the calorific value of the petrol as; 44770KJ/kg.
