Slider $C$ has a weight of $0.5 \mathrm{lb}$ and may move in a slot cut in arm $A B$, which rotates at the constant rate $\theta_0=10 \mathrm{rad} / \mathrm{s}$ in a horizontal plane. The slider is attached to a spring of constant $k=2.5 \mathrm{lb} / \mathrm{ft}$, which is unstretched when $r=0$. Knowing that the slider is released from rest with no radial velocity in the position $r=18$ in. and neglecting friction, determine for the position $r=12 \mathrm{in}$. (a) the radial and transverse components of the velocity of the slider, $(b)$ the radial and transverse components of its acceleration, $(c)$ the horizontal force exerted on the slider by arm $A B$.

Solution

Verified$\textbf{Knowns}$:

As shown in fig. P12.73 Slider C has a weight of $W_C$ =0.5 lb and may move in a slot cut in arm AB, which rotates at the constant rate $\dot{\theta_o}$ =10 rad/s in a horizontal plane.

The slider is attached to a spring of constant k = 2.5 lb/ft, which is un-stretched when r = 0.

Knowing that the slider is released from rest with no radial velocity in the position r = 18 in.
