A 6-module, 20° pinion of 20 teeth drives a rack. Calculate the pitch radius, base radius, working depth, whole depth, and tooth thickness of the rack on the pitch line.
A mass weighs 15 Newtons on the moon, where the acceleration of gravity is 1.67 m/s^2. Determine the weight, in Newtons, on Mars where g= 4.23 m/s^2
Examples of materials that have directional properties as a single crystal but are isotropic in their polycrystalline form.
the shaft consists of two sections with 8.5 knm of torque applied clockwise at the joint. the left steel section has a
an air-standard otto cycle uses 0.1 kg of air and has a clearance of 17%. THe intake conditions are 98 kPa and 37 C and the energy released during combustion is 1600 KJ/kg. What is the compression ratio of the cycle?
A spring stiffness k= 500 n/m is mounted against a 10 kg block. if the block is subjected to a force of 1 KN determine the velocity of the block at s=0.3 m when s=0, the block is at rest and the spring is uncompressed. The coefficient of fricktion is..

consider a piston-cylinder device that contains 0.5m3 of saturated water vapor at 0.2mpa and where the piston initially
steam enters a turbine operating at steady state with a mass flow 10 kgmin a specific enthalpy 3100 kjkg and a velocity
Force and Torque on a Dam. A dam has the shape of a rectangular solid. The side facing the lake has area A and height H. The surface of the freshwater lake behind the dam is at the top of the dam.
Water, initially a saturated vapor at 150 degrees Celsius, is contained in a piston-cylinder assembly. The water undergoes a polytrophic process (n=1) to a pressure of 0.01 MPa, during which the piston moves freely in the cylinder.
4 kW motor is driving an oil pump with an efficiency of 95% in a 10 mm diameter pipe. If the velocities of the fluid in the pipe is 1.8 m/s. What is the flow rate that the pump delivers?
Water vapor at 6 MPa, 600°C enters a turbine operating at steady state and expands adiabatically to 10 kPa. The mass flow rate is 2 kg/s and the isentropic turbine efficiency is 94.7%. Kinetic and potential energy effects are negligible. Determine..
