Answer to Question #104203 in Physics for Mathangi

Question

An equal force of 100 N is applied upon two similar sharp nails at different angles as shown in figure ⇒



What will be the ratio of pressures at the tip of the nail in figure(I) and figure(II)?

Answer 1

You have not provided the figure but I will try to provide you a method how to calculate the pressure if the area and force are not perpendicular

In cases when force and are aren't perpendicular we resolve either force or area vector whichever is easy in two direction one component tangential and the other one perpendicular(normal) to the surface

and then calculate the pressure = $\dfrac{force}{perpendicular(normal) \ area }$
