Final answer:
Hydraulic systems are used in heavy machinery like backhoes to lift and support heavy loads. The force exerted by the secondary cylinder can be calculated using the weight of the load and principles of equilibrium. The pressure in the hydraulic fluid can be found by dividing the force exerted by the cylinder by its cross-sectional area.
Step-by-step explanation:
Hydraulic systems are used in heavy machinery like backhoes to lift and support heavy loads.
To determine the force the secondary cylinder must exert, you can calculate the weight of the load and apply the principles of equilibrium
The pressure in the hydraulic fluid can be found by using the formula F/A, where F is the force exerted by the cylinder and A is its cross-sectional area.
In this case, the force can be calculated by multiplying the weight of the load by the acceleration due to gravity.
The pressure can then be found by dividing this force by the area of the cylinder.
For the lever system, you can use the formula P=F/A to find the force that needs to be exerted on the lever. In this case, you can calculate the force by multiplying the pressure by the area of the primary cylinder.
