The motion of peg p is constrained through the lemniscate, Ask an Expert

Academics

Q. What is the tangential acceleration of a bug on the rim of a 11.0 in. diameter disk if the disk moves from rest to an angular speed of 76 rev/min in 5.0 s?

Q. The motion of peg P is constrained by the lemniscate curved slot in OB and by the slotted arm OA.

If OA rotates counterclockwise with an angular velocity of dot theta = (3t^{3/2}); rm rad/s, where t is in seconds, determine the magnitude of the velocity of peg P at theta = 30^circ. When t = 0, theta = 0^circ.
