Answer:
The mechanical advantage is 3 to 1
Explanation:
A frictionless pulley with three support ropes carries equal tension on each of the ropes thus;
Tension in each pulley rope = T
Total tension in the 3 ropes = 3 × T = 3·T
Direction of the tension forces on each rope = Unidirectional
Total force provided by the 3 ropes = 3·T
Therefore, a force, T, applied at the end of the rope will result in a lifting force of 3·T
Hence, the mechanical advantage = 3·T to T which is presented as follows;
The mechanical advantage = 3 to 1.
Answer:
So the bouy does not float with its axis vertical
Explanation:
From the question we are told that:
Diameter
Length
Weight
Specific weight of sea water
Generally the equation for weight of cylinder is mathematically given by
Weight of cylinder = buoyancy Force
Where
Therefore
Therefore
Center of Bouyance B
Center of Gravity
Generally the equation for\BM is mathematically given by
Therefore
Therefore
Therefore
So the bouy does not float with its axis vertical
