- Relevant Equations
- Buoyant Force

A Spherical buoy has a diameter of 2m and weighs 3kN. It is designed to be used in a variety or circumstances by it being floated in water and anchored to the floor with a chain. Draw the free body diagram and determine the following given that the volume of a sphere is,

Volume = πD3/6

1.

Equation

Pf * Vd * g

Fb=Pf * Vd * g=(1.042kg/m3)(4.188m3)(9.81m/s2)

=42.8N

Is this correct? Trying to learn this. I think it is correct. But wanted to check so i understand how to do it correctly.

Then i am going to find question 2.

Question 2:

T = W - Fb

W = Weight

Fb = Buoyant Force

T = 3 - 42.8 = 39.8N

Tension = 39.8N

Is the Tension in the chain correct?

Volume = πD3/6

- The upthrust or buoyant force (Fb) in sea water.
- The tension in the chain (T)
