Question

EMCH 212/212H Rigid Body Angular Momentum & Work-Energy Square Crate Tipping Over With Plastic Impact A uniform square crate is released from rest with corner D directly above A and it rotates about A until its corner B impacts the floor and then it rotates about B. The floor is rough enough to prevent slipping and the corner at B does not rebound on impact. Determine, (a) as a function of g and 1, the angular velocity of the crate ω2 just before impact. (b) as a function of ώ2, the angular velocity of the crate immediately after impact a3. (c) the fraction of energy lost during the impact. (d) the maximum θ achieved after the impact During the impact, assume that the weight force is non-impulsive. Answers: 15 a3 --02: fraction energy lost- 4
