Draw the cam profile from the following data if the radial follower moves with simple harmonic motion during ascent and uniform acceleration and deceleration during descent: \(L\) ift \(=40 \mathrm{~mm}\), Least radius of cam \(=60 \mathrm{~mm}\), Angle of ascent \(=54^{\circ}\), Dwell \(=40^{\circ}\), Angle of descent \(=72^{\circ}\), Roller diameter \(=20 \mathrm{~mm}\).
