The person in the drawing is standing on crutches. Assume that the force exerted on each crutch by the ground is directed along the crutch, as the force vectors in the drawing indicate. If the coefficient of static friction between a crutch and the ground is 0.944, determine the largest angle MAX that the crutch can have just before it begins to slip on the floor.

A dancer is standing on one leg on a drawbridge that is about to open. The coefficients of static and kinetic friction between the drawbridge and the dancer's foot are μsμsmu_s and μkμkmu_k, respectively. n⃗ n→n_vec represents the normal force exerted on the dancer by the bridge, and F⃗ gF→g represents the gravitational force exerted on the dancer, as shown in the drawing.(Figure 1) For all the questions, we can assume that the bridge is a perfectly flat surface and...
