Question

A round 20-kg wheel is being rolled up a hill by force F causing its centroid (G) to accelerate in the directions shown.

WHEEL [9 pts] A round 20-kg wheel is being rolled up a hill by force F causing its centroid (G) to accelerate in the directions shown. You are asked to solve the problem using Newtonian Kinetics (F ma and M Ia). For each box in the table below fill in the correct signs [negative O, zero (0), or positive Gy Gx Point Term Angular acceleration If YM about point the change in angular kinetic term (la related to horizontal acceleration of centroid (ac is If YM about point the change in angular kinetic term (Ia) related to vertical acceleration of centroid (acy is

Explanation / Answer

Angular acceleration: Point A (+), Point C (+), Point D (-)

Mass (related to horizantal acceleration): Point A (0), Point C (+), Point D (+)

Mass (related to vertical acceleration): Point A (+), Point C (0), Point D (+)
