Two identical cars A and B are at rest on a loading dock with brakes released. Car C, of a slightly different style but the same weight, has been pushed by dockworkers and hits car B with a velocity of 4.5 ft/s. Knowing that the coefficient of restitution is 0.8 between B and C, and 0.5 between A and B, Determine the velocity of each car after all collisions have taken place.
Two kilograms of air within a piston-cylinder assembly execute a carnot power cycle with maximum and minimum temperatures of 750k and 300k, respectively.
Assignment on kinematic chains - Type of chain whether it is locked,constrained or unconstrained?
Sketch the thermal circuit of the system. Label (using the above symbols) all pertinent nodes and resistances.
A connection of rod of 50 mm diameter has a rectangular block 50 mm wide and 25mm thick forged at its end. A turned radius of 25 mm joins the rod and the block. Draw the projections of the rod showing curves of intersection.
As shown, a 130 lb bungee jumper wants to jump from the top of a 655 ft high bridge and be able to just touch the water below. Given that the bungee cord has a spring constant of 2.33 lb/ft, what should the bungee cord's relaxed length, l, be for ..

what is the effect of quenching on the transition temperature and toughness for the mild steel ?
A steel alloy to be used for a spring application must have a modulus of resilience of at least 2.07 MPa (300 psi). What must be its minimum yield strength?
If the deflection of the gae fluid height, h, is 2 inches find the 1) velocity of the jet air and 2) the force exerted on the disk by the air.
Show that the spacing between (111) planes in the FCC structure is the same as the spacing (002) planes in the HCP structure. Imagine the atoms to behave as hard spheres.
A steel rod 1 cm in diameter and 30 cm long protrudes from a steel surface at 150 C. The rod is surrounded by air at 10 C with a convective heat transfer coefficient of 10 W/m2 C. The thermal conductivity of steel is 114 W/m C. Determine the heat ..
