The graph for the motion of a train as it moves from station A to station B is shown. Draw the a-t graph and determine the average speed and the distance between the stations.
Determine the acceleration of the cabinet when sA = 40 ft. Note that when sB = 0, sA = 0 (points A and B are coincident).
The wheel of a crane lift is rolling on a flat rail. The radius of the wheel is 4 in, the contact length and force are 2.5 in and 1 ton respectively, and E = 30 MPa and ν = 0.3 for both parts. Determine (a) the maximum contact pressure, (b) the wi..
What is hogr? How much steam pressure is required to maintain adequate vacuum with it? Where are hogr used in general?
you are given a task of compressing a fixed quantity of gas from P1,T1 to P2,T1. you wish to do this using a polytropic process coupled with a constant pressure P2 heat-transfer process. determine the polytropic process that minimizes the entropy ..
Using a centrifugal pump, and a flow rate of 60 gal/min, calculate the break hp of the pump using water with a density of 62.4lbm/ft3 and do the same for a nonviscous liquid having a density of 0.85g/cm3.
Determine the rate of metal removal when the wheel is engaged in the work and if the number of active grits per square inch = 200, determine the average chip length and the number of chips formed per time
Define- hydraulic mean radius, hydraulic dept, section factor and most efficient dhannel cross section.
Also determine the axial force and deformation of the diameter due to temperature rise. Let E = 120 GPa and Co-efficient of linear thermal expansion = 0.0000168 per °C.
If the beam has square cross section of 9 in., on each side, determine the absolute maximum bending stress in the beam.
Cracks propagate when the stress intensity factor exceeds a critical value and describe the fracture behaviour of the insulation tape loaded with a small crack.
Assume you are given a spherical joint where the ball has a radius of 20 mm and socket has a radius of 22 mm. If the contact load is 50 N, E = 210 GPa, and ν = 0.3, determine (a) the radius of the contact area, (b) the maximum contact pressure.
