Answer:
Pressure,
Explanation:
Given that,
Force with which pickaxe strikes is 3600 N
The end of the pickaxe measure 15mm by 13mm.
We need to find the pressure exerted on the pipe by the pickaxe. Pressure exerted is equal to the force acting per unit area. So,
A = 15 mm × 13 mm = 195 mm² = 0.000195 m²
So,
<h2>
So, the pressure of is exerted on the pipe by the pickaxe.</h2>
