Question

Question 24
Consider a vertical piston/cylinder system. The piston has 50 g mass and a given radius of 3 cm. What is the pressure due to the piston?

Answer 1

Explanation:

Mass=50g

Weight=thrust=50gf

Radius=3cm

Area=pie×r sq

=pie×3 sq

=pie× 9

=3.14×9

=28.26cmsq

Pressure=Thr/Area=50gf/28.26cmsq=1.76gf/cmsq (approx)

In my opinion...the ans is 1.76gf/cmsq(approx)....hope u agree with the ans....if so....please comment and thanku
