A piston of mass $2 \mathrm{kg}$ is lowered $0.5 \mathrm{m}$ in the standard gravitational field. Find the required force and the work involved in the process.
Added by Hayden C.
Step 1
The weight of an object is given by the formula W = mg, where m is the mass of the object and g is the acceleration due to gravity. Here, m = 2 kg and g = 9.8 m/s² (standard value). So, W = 2 kg * 9.8 m/s² = 19.6 N. This is the force required to lower the piston. Show more…

A steel piston of mass 10 lbm is in the standard gravitational field, where a force of $10 \mathrm{lbf}$ is applied vertically up. Find the acceleration of the piston.
The hydraulic lift shown in the figure below has a small piston with surface area A1 = 0.039 m² and a large piston with surface area A2 = 5.0 m². The input force F1 = 21 N. How much work is done in slowly pushing down the small piston if Δy1 = 0.25 m?

"In a hydraulic lift, the input piston has surface area 20 cm². The output piston has surface area 1000 cm². If a force of 50 N is applied to the input piston, it raises the output piston by 2 m. Calculate the weight of the support on the output piston and the work done by it"
