Answer:
55738.539 Pa
Explanation:
Gvien:
The mass of the man = 73 kg
Mass of the chair = 7.4 kg
radius of the leg of the chair = 1.5 cm = 0.015 m
Now,
the force of gravity due to both the masses, F = (73+7.4) kg x 9.8 = 787.92 N
Also,
Pressure = force / area
Area of a circle of leg = πr² = π x 0.015² = 7.068 x10⁻⁴ m2
Now,
there are 2 legs so the force will be divided evenly in each leg
thus,
F' = ![\frac{787.92}{2}=393.96N](https://tex.z-dn.net/?f=%5Cfrac%7B787.92%7D%7B2%7D%3D393.96N)
Hence, the pressure on each leg will be
Pressure = ![\frac{393.96N}{7.068\times 10^{-4}}=55738.539 Pa](https://tex.z-dn.net/?f=%5Cfrac%7B393.96N%7D%7B7.068%5Ctimes%2010%5E%7B-4%7D%7D%3D55738.539%20Pa)
Answer:
It’s pretty self explanatory I hope this helps
