Question

You’re hanging from a chinning bar, with your arms at
right angles to each other. The magnitudes of the forces
exerted by both your arms are the same, and together they

(a) Sketch the two force vectors for your arms, along with their
resultant, and (b) use components to find the magnitude of
each of the two “arm” force vectors.
