Cam Curve Design
Design a three-dwell cam to move a follower from 0 to 2.5" in 40deg, dwell for 100deg, fall 1.5" in 90deg, dwell for 20deg, fall 1" in 30deg, and dwell for the remainder. The total cycle must take 10sec. Plot the s,v,a,j diagrams. The polynomial method is to be used to solve the equation. For the graphs, Mathcad or similar program is necessary to graph the solution.
Module FEA - FINITE ELEMENT ANALYSIS , Provide answers to all questions. Note that assignment part 2 carries 60% of the marks for the course.
A spur gear has 48 teeth with a diametral pitch of 8 and a pressure angle of 20 deg. The face width is 0.75 inches. If the gear is transmitting 25 HP at 250 rpm
Steam enters the turbine of a simple vapor power plant with a pressure of 160 bar and a temp of 560 C and expands adiabatically to 0.08 bar
Show how did you do the maintenance during your workshop
Find the needed length of the heated section of the tube and find the temperature of the water when it exits the heated section of the tube.
Motor coming to rest, A motor is running at 12 rpm and the switch is flipped and cuts the power. The rotor weighs 75 lbs.
this would provide you with a set of Reynolds numbers. Next, using the integral method, determine the velocity profiles within the boundary layer to be followed by determination of the heat transfer coefficient values for your selected Reynolds numbe..
Fluid/Dam Pressure, Compare the pressure force exerted on the face of two dams that hold a fresh water of 1000 Kg/m^3 density and a salty water of 1030 Kg/m^3
A linear isotropic material has the shear modulus of elasticity G of 11.5*10^6 psi and the Poisson's constant v of 0.3.
Aeroplane Dynamics, Determine the steady thrust that would enable a 200-tonne airliner to reach its take-off speed (75 m sâ?'1), from rest, in 30 s
A rigid vessel of capacity 0.6 m3 contains dry saturated steam at 4.0 bar. The vessel is cooled until the pressure is reduced to 2.0 bar, Calculate; a) the mass of steam in the vessel.
Determine the coordinates x' and y' of the centroid C of the area shown in the figure and calculate the moments of inertia of the area shown, about ox and oy axes.
