A 50 kg stcel ball is hanging from two cables that make 120 degrees with each
FrozenT [24]

Answer:

T1 = 490.5 [N], T2 = 490.5[N]

Explanation:

First, we must draw a free body diagram of the steel ball hanging and the two wires holding it as well as the angle forming the wires between them.

The free-body diagram can be seen in the attached image.

As the cables are symmetrical with respect to the vertical axis, the force in cables 1 and 2 is equal, so when performing a force sum equal to zero on the Y-axis, we can find the force value of any cable.

The solution of the equations can be seen in the attached image

2.19 The drag characteristics of a blimp traveling at 4 m/s are to be studied by experiments in a water tunnel. The prototype is
Naily [24]

Answer:

Vm=0.894m/s

Explanation:

From the question we are told that

Velocity if travel v=4m/s

Diameter of  prototype d_1=20m and d_2=110m

Scale ratio=\frac{1}{20}

Generally Velocity of of the model using Froud's model is mathematically given as

Fm=Fp

\frac{Vm}{\sqrt{Lmg}} =\frac{Vp}{\sqrt{Lpg}}

Vm=Vp*\frac{Vp}{\sqrt{Lpg} }

Vm=4*\frac{1}{\sqrt{20}}

Vm=0.894m/s
