Include the solution of the problems with the whole procedure clear, complete and organized. As shown in the examples in the lesson.
Solve:
1. If the box has a weight of 70 N, determine the voltages T1, T2 and T3.
2. The following system is in rotational equilibrium. If the cylinder has a weight of 6.0 N, find the weight of spheres A, B, and C.
3. In a car lift in a service station, the compressed air exerts a force on a small piston that has a radius of 8.00 cm. This pressure is transmitted by a liquid to a piston that has a radius of 18.0 cm. (a) What force must the compressed air exert to raise the car that has a weight of 13,300 N. (b) What pressure does this force produce?
0 450 T2 T1 T3
Solution
1) using the sine law we have
T3 = W = 70 N
T3 /sin 105 = T2 / sin 135 = T1 / sin 120
T2 = 70 * sin 135 / sin 105 = 51.24 N
T1 = 70*sin 120 / sin 105 = 62.76 N
