Answer:
A_1 = 0.0135 m2
Explanation:
GIVEN DATA:
mass of SECOND truck m2 =2500 kg
mass of FIRST truck m1 = 25 lb = 11.33kg
Area A2 = 3 m2
according to the pascal's law, pressure at one point is equal to pressure exerted on the other side, therefore we have
[tex]P_{1 }= P_{2}[/tex]
we know that
[tex]pressure = \frac{force}{area}[/tex]
[tex]\frac{f_{1}}{A_{1}} =\frac{f_{2}}{A_{2}}[/tex]
[tex]A_{2} =\frac{f_{2}}{F_{1}}* A_{1}[/tex]
[tex]A_{2} = \frac{m_{2}}{m_{1}}*A_{1}[/tex]
[tex]3 = \frac{2500}{11.33}*A_{1}[/tex]
A_1 = 0.0135 m2
