A cable that can withstand 2,250 pounds is used to pull cargo up an inclined ramp. If the inclination of
the ramp is 21.5°, what is the heaviest piece of cargo that can be pulled up the ramp, ignoring friction?

A. 825 pounds
B. 2,090 pounds
C. 6,140 pounds
D. 2,420 pounds

    If θ is the inclination with the horizontal, ignoring friction, and assuming 2250 pounds is the working load, then the heaviest cargo it can pull is
    W=2250/sin(θ°)
