The piston in the cylinder head of a locomotive has a stroke (twice the amplitude) of 1.0m. If the piston moves with simple harmonic motion with an angular frequency of `200rev//`min., what is its maximum speed ? |
Answer» Stroke of piston =2 times the amplitude Let A = amplitude, stroke = 1m `:. rArr A = (1)/(2)m` Angular frequency, `omega = 200 rad//min`. `V_(max) = ?` We know that the maximum speed of the block when the amplitude is A, `V_(max) = omega A = 200 xx (1)/(2) = 100 m//min`. `=(100)/(60) = (5)/(3) ms^(-1) = 1.67 ms^(-1)` |
