What pressure does a table weighing 100H produce on the floor if the area of its legs is 50cm ^ 2?
March 11, 2021 | education
| Given:
F = 100 Newton – the weight of the table standing on the floor;
s = 50 square centimeters – the total area of the table legs.
It is required to determine P (Pascal) – the pressure that the table produces on the floor.
We convert the units of measurement of area from square centimeters to square meters:
s = 50 cm2 = 50 * 10 ^ -4 = 0.005 square meters.
Then, to determine the pressure of the table on the floor, you must use the following formula:
F = P * s, from here we find:
P = F / s = 100 / 0.005 = 20,000 Pascal = 20 kPa.
Answer: the table exerts a pressure on the floor equal to 20 kPa.
