I just need someone to tell me if I've done the problem right since the answer is mysteriously missing [8)]
The question is about a rotating wheel causing a piston to execute SHM inside a cylinder (the piston being connected to the outside of the wheel). The wheel rotates with an angular speed of 12rads-1 and it has a radius of 30cm.
What will be the distance of the piston from an end position after 0.10s?
ω = θ/t
θ = 12x0.1 = 1.2rad
displacement from equilibrium point = amplitudexCosθ = 0.3xCos1.2 =0.1087m
so distance from end position = 0.3-0.1087 = 0.19m (2sf)
