Question
The hydraulic system of a backhoe is used to lift a load as shown in Figure 11.48. (a) Calculate the force $F_s$ the slave cylinder must exert to support the 400-kg load and the 150-kg brace and shovel. (b) What is the pressure in the hydraulic fluid if the slave cylinder is 2.50 cm in diameter? (c) What force would you have to exert on a lever with a mechanical advantage of 5.00 acting on a master cylinder 0.800 cm in diameter to create this pressure?
1. $1.38 \times 10^4 \textrm{ N}$
2. $2.81 \times 10^7 \textrm{ Pa}$
3. $283 \textrm{ N}$
