In figure B, a standard man (mass = 70 kg) uses crutched. The crutches each make an angle of = 250 with the vertical. Half the standard man’s weight is supported by the crutches; the other half is supported by the normal force acting on the sole of the feet. Assuming the standard man is motionless, calculate the magnitude of the force supported by each crutch

Given the vector

Vector T is the unit tangent vector, so the derivative r(t) is needed.

Vector N is the normal unit vector, and the equation for it uses the derivative of T(t).

The B vector is the binormal vector, which is a crossproduct of T and N.
