Ans: $($a$)352\mathrm{.}767$ lb $($b$)1613\mathrm{.}13$ lb $($c$)1010\mathrm{.}74$ lb Tension or Compression? You tell me$.$

Use both the $1-$D constraint equation method and the polar coordinates method to do

kinematics and cross compare. The $5000$ lb truck A is pulling the $800-lb$ block $B$ on the $1000-$

lb wedge cart C anchored to the ground by using the pulley$-$and$-$cable arrangement shown.

Friction coefficients are indicated. If at the instant, block $B$ has the motion shown, determine

$($a$)$ the tension in the cable, $($b$)$ the ground traction on the truck, and $($c$)$ the force in the pin$-$Connected link $($indicate tension or compression$).$ Note that the $17\text{'}$ length shown in the picture

is only the instantaneous value. In $($c$),$ there are two ways to draw the FBD$.$ One way is to

isolate C only, and the other is to isolate both B and C in a system $($with a hybrid KD $).$ Use

both methods and cross compare. In $($b$),$ also check if the traction your find is above what the

ground can provide or not.
