Learning Goal: A circular cam is in contact with a rectangular lifter and used to intermittently operate a piece of equipment at the end of a lifter arm. The lifter is in contact with the highest point of the cam at the instant shown and the lifter is constrained to move only in the vertical direction. The cam has a radius of r=4.0in and is rotating about point O, which is offset from the center by a distance c=2.3 in. The cam's angular position is measured from the positive x axis and is positive clockwise. The angular velocity and acceleration are positive clockwise. (Figure 1) Figure 1 of 1
Find the range of θ for which the position equation s=r+csin(θ) is valid if the width of the lifter is w=222 in and its right edge is aligned with 0 . Give only the range values that lie between 0∘ and 180∘ Express your answers in degrees, separated by a comma, to two significant figures.
