A barber raises his customer chair by appling aforce of 150N to hydravilic piston of area 0.01m2 if the cair is attached to apiston of area 0.1m2. how mass customer the chair is 5kg ?

To solve this problem, first determine the force applied to the larger piston.

F=> (A²/A¹) F¹

F=> (0.10m²/0.01m²) (150N) = 1500N

=>153kg

barber chair force

If the maximum force on the chair is 1500N, you can now determine the maximum mass which can be lifted by recognizing that the force that must be overcome to lift the customer is the force of gravity, therefore the applied force on the customer must equal the force of gravity on the customer.

F=> mg

M=> (f/g) = (1500N/9.8²)

barber chair mass

If the chair has a mass of 5 kilograms, the maximum mass of a customer in the chair must be 148 kg.
