Bar AB has a cross-sectional area A = 100 mm2 and modulus of elasticity E = 102 GPa. The distance H = 400 mm. If a 200 kN downward force is applied to bar CD at D, through what angle (in degrees) does bar CD rotate? Because the deformations are small, you can assume that the point B displaces downward vertically. (Bar AB is deformable, and bar CD is rigid.)

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above
