Determine the load that can be lifted by the system shown in Problem 10.22 if R1 is reduced to 4 cm.

10.22 Determine the load that can be lifted by the hydraulic system shown in the accompanying figure. All of the necessary information is shown in the figure.

Chapter 10, Problem 23P, Determine the load that can be lifted by the system shown in Problem 10.22 if R1 is reduced to 4 cm.

To determine

Find the load which is lifted by the hydraulic system.

Explanation of Solution

Given data:

Input force F1 is 1000 N.

Radius of small area piston r1 is 4 cm.

Radius of large area piston r2 is 20 cm.

Formula used:

Formula to determine the output force is,

F2=A2(F1A1) (1)

Here,

F1 is the input force,

A1 is the area of smaller piston, and

A2 is the area of larger piston.

Formula to determine the weight of the load is,

m2=F2g (2)

Here,

F2 is the output force, and

g is the acceleration due to gravity.

Formula to determine the smaller piston area is,

A1=πr12 (3)

Substitute 0.04 m for r1 in equation (3).

A1=π(0.04m)2=5.026×103m2

Formula to determine the larger piston area is,

A2=πr22 (4)

Substitute 0.2 m for r2 in equation (4).

A2=π(0
