Question:

Finding net force on a beam and its acceleration?

A crane lifts a 190 kg steel beam, applying a 2150 N vertical force.Find the net force on the beam.Find the beam's acceleration.

Answer:

Sulfur has 6 outer-shell electrons Fluorine has 7 outer-shell electrons 3 shells in bohr model of aluminium c) 2,8,7 c)same number of electron shells
Gravity acts downward on the beam with a force of 190 kg x 9.81 m/s^2 1864 N Net force 2150 N - 1864 N 286 N upward a f/m a 286 N / 190 kg a 1.51 m/s^2 upward
