Three forces are applied to a wheel of radius 0.350 mm, as shown in the figure below. One force is perpendicular to the rim, one is tangent to it, and the other one makes a 40.0 degrees angle with the radius.

A vertical solid disk of uniform mass ?=7kgM=7kg and radius ?=0.5mR=0.5m is pivoted from point ?O as shown in the figure below. A constant radial force of ?=117NF=117N is applied where the angle ?=36?β=36o. If ?=0.36mx=0.36m, determine the angular acceleration of the disk in SI units at the instant shown. Express your answer using two decimal places. Please use the convention: Clockwise (-), Counterclockwise (+) when expressing your answer. Hint 1: The moment of inertia of a uniform disk about an axis of rotation passing through the center of mass (CM) is ???=??2/2ICM=MR2/2. Hint 2: Don't forget the force of gravity!!!
