1. The problem statement, all variables and given/known data Consider the simplified single-piston engine in the figure. The wheel rotates at a constant angular speed of 1 rad/s and the radius of the wheel is 2 m. If the piston is fully extended at time t=0, find the position of the piston at 2s. The figure depicts a wheel with a peg that draws a piston in and out of a bore as the wheel rotates (counter clockwise, with the piston horizontal to the right). 2. Relevant equations x=A cos (omega*t) where A is the radius of the wheel 3. The attempt at a solution omega*t = 2rad cos 2 * 2m = x. since 2 > pi/2, I add 2meters to the resulting x. The answer I get is reportedly wrong. what's wrong with my approach?
