2. A 15-kg slender bar OA is released from rest in the purely vertical position* and compresses the spring of stiffness k = 20 kN/m as the horizontal position is passed. The spring height h can be adjusted via a thumb screw. a. If we desire the bar to have an angular velocity of 4 rad/s as it crosses the horizontal, what should h be 600 mm set to? b. How does the design choice of the position x affect these calculations? *Parallax of my scan misleads a little. The bar starts at a straight vertical position. x = 400 mm
A disk with radius R and mass m begins from rest and then moves without slipping while being pulled horizontall by a force P acting at its center axle. Show that the velocity of the wheel after T seconds is v= 2PT/3m. (Hint: use both linear and angular-impulse principles.) m REG P ¹The radius of gyration has units of length and is related to the inertia by k = IG/m. It corresponds to the distance at which a mass equivalent to the mass of the rigid body would produce the same inertia as the actual rigid body. Recall that the inertia of a particle of mass m at a distance r from an axis of ortation is mr². Rather that using r the convention is to define the radus of gyration with the symbol k.
