Ответ:
applied force on piston is 302.308163 N
Explanation:
Given data
mass = 1510 kg
weight = 1510 × 9.81 = 14813.1 N
radius = 8 cm
piston = 1.0 cm
to find out
force
solution
we will apply here pascal principal i.e
weight of automobile / area 1 = applied force on piston / area 2
so applied force on piston = weight of automobile × area 2 / area 1
and we know that areas is proportional to square of diameter
so area 2 / area 1 = (0.01/0.08)²
so applied force on piston = weight of automobile × (0.01/0.08)²
applied force on piston = 14813.1 × (0.01/0.07)²
applied force on piston is 302.308163 N
