(2) Theoretical data:
when n =0, the tension F of the steel wire rope is the resultant force of the component force and the friction force of the weight of the steel wire rope in the inclined shaft:
F=m(sinθ+μcosθ)
m-wire rope mass, m =100 × 4.30=430 (kg);
theta is inclined shaft inclination angle, theta =30 degrees;
