Can crushers help us recycle in a space efficient way which is good for saving the earth and for giving you more room in your apartment. Let us model the illustrated crusher as a planar mechanism that is subjected to the pushing force on the lower "L-shaped" handle, i. e. link CDE. Note that link CDE is one solid piece, pinned at D and E. Knowing that the orange horizontal member has a square peg at that slides vertically in the slot on the blue frame, that the can is centered under the pin at and that N, , , mm, mm, mm, and mm, determine the force magnitude in N exerted on the can from the mechanism.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Determine the damped natural frequencies and the steady state response of a decoupled damped forced two degrees of freedom system. 10ä1 + 2q1 20q1 10 cos t; 10q2 +4q2 + 40q2 10 cos t

Asimple rankine cycle uses water as the working fluid. the water enters the turbine at 10 mpa and 480c while the condenser operates at 6 kpa. if the turbine has an isentropic efficiency of 80 percent while the pump has an isentropic efficiency of 70 percent determine the thermal efficiency
