Homework Statement



Using the diagram shown below for a simple reciprocating engine, determine (a) the piston velocity (velocity at point D) and (b) the piston acceleration (acceleration at point D) as functions of the crankshaft angle, θ. The dimensions are as follows: LAB=1.875”, LBD=6.0”, and ωAB=8000rpm. (c) Plot your results: VD vs. θ and AD vs. θ.

Hmmm, you want help on an extra credit problem that you "don't know where to start" so you can hand it in for extra credit. What's wrong with this picture? Under those circumstances I will give you only one small hint, which is probably more than I should do:

Call AD "x" and write x in terms of the known sides and angle. And use letters instead of numbers until the end.
