Homework Help: Math

Posted by jof on Friday, March 30, 2012 at 12:53pm.

The position of a car piston within the cylinder is described by the equation:
y = S sin(360

r t - 90
Where S is the stroke length of the cylinder, r is the rpm of the crank shaft, and t is
the time in minutes. If the stroke length is 2 inches and the crank shaft is running at
1300 rpm, find the position of the piston at t = 53 seconds. (remember that rpm
means revolutions per minute)
