A 82kg man sits on a 3.9kg chair. Each leg of the chair makes contact with floor in a circle = 1.4cm in diamet - exerted pressure by a chair leg
82 kg A man sits in a chair kg to 3.9. Each leg of the stool is brought into contact with the floor in a circle = 1.4cm in diameter.
Find the pressure on the bottom for each leg of the chair, the assumption that the weight is evenly distributed.
P = __

Exerted Pressure By A Chair Leg A 82kg Man Sits On A 3.9kg Chair. Each Leg Of The Chair Makes Contact With Floor In A Circle = 1.4cm In Diamet

Thus, 85.9 kilograms and 21.5 kilograms divided into 4 per leg
This corresponds to 210 N
The contact area on the leg
= 1.4cm in diameter, radius = 0.7 cm = 0.007m
A = πr ² = ² = 0.000154 m² π0.007
then the pressure is 210 or 1,364,000 sq Pascal N/0.000154
