The maximum pressure angle happens at approximately 91.2º. For this angle of the camshaft, calculate the pressure angle (Φ) using a base circle radius of 2.5", a roller radius of 0.5", and an eccentricity of 0.1". Include the sign and report your answer in degrees, rounded to two decimal place

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

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.

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.
