] Use graph paper to draw simplified sketch of the gear and the rack shown in problem 5/64(79). What are the three angles belonging to the triangle formed by AB, radius of the wheel, and horizontal line between center of the gear and point A. [b] Redraw when the rack AB is at 45o angle. What are the other two angles belonging to the triangle formed by AB, radius of the wheel, and horizontal line between center of the gear and point A. [c] Redraw when the rack AB is at 89o angle. What are the other two angles belonging to the triangle formed by AB, radius of the wheel, and horizontal line between center of the gear and point A.
[a] Use graph paper to draw simplified sketch of the gear and the rack shown in problem 5/64(79). What are the three angles belonging to the triangle formed by AB, radius of the wheel, and horizontal line between center of the gear and point A.
[b] Redraw when the rack AB is at 45o angle. What are the other two angles belonging to the triangle formed by AB, radius of the wheel, and horizontal line between center of the gear and point A.
[c] Redraw when the rack AB is at 89o angle. What are the other two angles belonging to the triangle formed by AB, radius of the wheel, and horizontal line between center of the gear and point A.
[d] Redraw when the rack AB is aproaches parallel to horizontal. What are the other two angles belonging to the triangle formed by AB, radius of the wheel, and horizontal line between center of the gear and point A. (Hint: Represent the gear by a circle and the rack by a line.)
