Static-equilibrium problem 8

The weightless horizontal bar in the figure below is in equilibrium. Scale B reads 4.20 kg (N.B. as you know, the scale should read N, but no one told manufacturer). The distance in the...

Static-equilibrium problem 3

The system in the figure is in equilibrium. A mass M1=234 kg hangs from the end of a uniform strut which is held at an angle θ=42.0° with respect to the horizontal. The cable...
