Auniform thin disk with a 6-in. diameter is attached to the end of a rod ab of negligible mass that is supported by a ball-and-socket joint at point a. knowing that the disk is spinning about its axis of symmetry ab at the rate of 2800 rpm in the sense indicated and that ab forms an angle β = 45° with the vertical axis ac, determine the two possible rates of steady precession of the disk about the axis ac.

What is the rate of change in a objects position?

The uniform slender bar rests on a smooth horizon- tal surface when a force f is applied normal to the bar at point a. point a is observed to have an initial acceleration aa of 20 m/s2, and the bar has a corre- sponding angular acceleration of 18 rad /s2. deter- mine the distance b.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
