The distance from TDC (top dead centre) for the pin is given by x when the crank is
at angle . Hence :
i) Give an equation for x in terms of the other variables (r, L and ).
ii) If the crank rod is rotating at a constant value of ω calculate the speed of the
in terms of ω, r, and L
iii) Hence calculate the x value when the speed of the piston is at a maximum.
iv) If L is 1 metre, r is 0.25 metres and the crank is rotating at 5,000 rpm
calculate the maximum velocity of the piston in m/s.
