Use the Head$-$to$-$Tail method for the HW assignment.

For $=10$ and $T=12kN$ determine the resultant vector. Give answer in magnitude and direction format.

A spring attached at $A$ is unstretched $($no force in spring$)$ when slider $P$ is at the top of the semicircular slot. Determine the force in the spring when slider $P$ is at position $=90.$ Then give the spring force at $P($directed towards $A)$ in rectangular components using unit vectors. Use $r=500mm$ and spring constant $k=1\mathrm{.}5k\frac{N}{m}.$
