Question

1. A workman weighs 850N, and each of his boats has an area of 210cm. Calculate the maximum pressure​

Answer 1

Answer ::

The maximum pressure is 404.77 Nm.

Explanation ::

To Find:-

• Maximum pressure

Solution:-

Given that,

• Magnitude of force a woman weighs = 850 Newton
• Area of contact = 210cm ... [ 210cm = 2.1m ]

As we know that,

$\dag \: \underline{ \boxed{ \red{\sf{Pressure = \dfrac{Force}{Area \: of \: contact}}}}}$

Therefore, the pressure is,

$\sf{ \mapsto \: Pressure = \dfrac{850}{2.1}} \\ \\ \\ \sf{ \mapsto \: Pressure = \cancel{\dfrac{850}{2.1}}} \\ \\ \\ \bf{ \mapsto \: Pressure = 404.77 \approx}$

Therefore, the pressure is 404.77 Nm.

More Information

• The S.I. unit of pressure is Pascal ( Pa )
• 1 Pa = 1 Nm·²
• The bigger unit used for measuring pressure is kilopascal ( kPa )
• 1 Pascal is numerically equal to the force of 1 Newton acting on an area of 1 metre square.
