Question

A piston of cross sectional area 100 cm is used in a hydraulic press

Answer 1

Formula to be used

= frac{force(f)}{area(a)} = \frac{f1}{a1} = \frac{f2}{a2}=> area(a)force(f)

= a1f1

= a2f2

____________________

Area (A1) = 100 cm²

: = \frac{100}{100 \times 100} = 0.01 \: {m}^{2}=

100×100

100

=0.01m

2

Force(F1) = 10^7 dynes =( 10^7 ×10^-5) N

= 100 \: newton=100newton
