Find the work done (in ft-lb) when a constant force F = 18 lb moves a chair from x = 0.6 to x = 1.4 ft.

The work done is 14.4 lb-ft

Explanation:

Given;

constant force, F = 18 lb

initial position of the chair, x₁ = 0.6 ft

final position of the block, x₂ = 1.4 ft

Work is said to be done, when an applied force moves an object through a distance.

W = F x d

where;

F is the applied force

d is the distance moved by the object

Distance moved by the object, d = x₂ - x₁

d = 1.4ft - 0.6 ft

d = 0.8 ft

W = F x d

W = 18 lb x 0.8 ft

W = 14.4 lb-ft

Therefore, the work done is 14.4 lb-ft

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
