The radii of the press plunger and the pump plunger are in the ratio \( 30: 4 . \) If an effort of 32 kgf acts on the pump plunger. Find the maximum effort the press plunger can overcome.
- A. \( 1600 \mathrm{kgf} \)
- B. 1700 kgf
- C. \( 1800 \mathrm{kgf} \)
- D. 1900 kgf
Step-by-step solution
Using Pascal's law for hydraulic press, the force is proportional to area. Radii ratio 30:4 gives area ratio (30^2)/(4^2)=900/16=56.25. Effort on pump plunger = 32 kgf, so force on press plunger = 32 * 56.25 = 1800 kgf.
