Static-equilibrium problem 4

Добавлено в закладки: 0

You are holding a ball of mass 108 g in your hand as shown in the figure.Your arm (length L=57 cm) is held in an outstretched horizontal position by action of the deltoid muscle, which applies its force at an angle of θ=17 degrees and at a distance L2=15 cm from the shoulder. The arm has a mass of 4.4 kg and its center of mass is a distance of 26.22 cm from the shoulder.

Solution of the example in word.
