Technician A measures valve lash on an OHC engine by rotating the engine to TDC for number 1 cylinder then measures the gap between the cam and tappet for all the valves. Technician B sets the engine at TDC for number 1 cylinder then measures the gap between the cam and tappet only on the valves that are closed. He then rotates the crankshaft 360 degrees and measures the gap between cam and tappet for the remaining valves. Who is correct?

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

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.
