A disk initially at rest is acted on by a constant net torque τ (think of this as force, F). The disk spins for a period of t seconds and rotates an angular distance of Δθ. The same disk is then brought to rest. The disk is now acted upon by a constant net torque 2τ (think of this as force, 2F). The disk spins for the same period of t seconds. What is the new angular distance the disk rotates?

Abeverage can is made of 3004-h19 aluminum alloy (elastic modulus 69 gpa, tensile yield strength 285 mpa, density 2.72 g/cm^3). the dimensions on the can are approximated as a thin-walled cylinder with a height of 4.83 inches, diameter of 2.60 inches. empty the can has a mass of 14.2 g. determine: a. the wall thickness of the cylinder b. assuming a pinned-pinned condition what is the critical load? c. assuming a fixed-fixed condition what is the critical load?
