Question

Consider a rotating disk cam and a translating roller follower with zero offset. Which one of the following pitch curves, parameterized by t, lying in the interval o to 2$\pi$, is associated with the maximum translation of the follower during one full rotation of the cam rotating about the center at (x,y ) =(0, 0)?

• A. $x\left(t\right)=cost,y\left(t\right)=sint$
• B. $x\left(t\right)=cost,y\left(t\right)=2sint$
• C. $x\left(t\right)=\frac{1}{2}+cost,y\left(t\right)=2sint$
• D. $x\left(t\right)=\frac{1}{2}+cost,y\left(t\right)=sint$

Answer 1

The correct option is C $x\left(t\right)=\frac{1}{2}+cost,y\left(t\right)=2sint$

$x\left(t\right)=\frac{1}{2}+cost,y\left(t\right)=2sint$
