Determine the weight of the bar if the area of its support is 0.05 sq. m, and the pressure that it produces is 4,800 Pa.

Given:

s = 0.05 m2 (square meters) – support area of the bar;

P = 4800 Pascal – the pressure that the bar produces.

It is required to determine F (Newton) – the weight of the bar.

To determine the weight of a bar, you must use the following formula:

P = F / s, from here we find that:

F = P * s;

F = 4800 * 0.05;

F = 48 * 5 = 240 Newtons.

Answer: the weight of the bar is 240 Newtons
