Question

Let us model the illustrated crusher as a planar mechanism that is subjected to the pushing force P 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 AB has a square peg at A that slides vertically in the slot on the blue frame, that the can is centered under the pin at B and that P-45 N, θ-10°, φ-15°, a-65 mm, b 240 mm, c = 65 mm, and d = 20 mm, determine the force magnitude F in N exerted on the can from the mechanism. ar Probdbly the oger in Cl.

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.
