garik1379 [7]

To develop the problem it is necessary to take into account the concepts related to Torque and sum of moments.

By torque it is understood that

\tau = F*d

Where,

F= Force

d = Distance

The value of the given Torque acts from the center of mass causing it to rotate clockwise.

The Force must then be located at the other end down to make a movement opposite the Torque in the center of mass.

I enclose a graph that allows us to understand the problem in a more didactic way.

The correct answer is D.

fgiga [73]

Answer:

Thus, the maximum height is 7.35 m.

Explanation:

initial velocity, u = 12 m/s

acceleration due to gravity, g = 9.8 m/s^2

Velocity at maximum height, v = 0 m/s

Let the maximum height is h.

Use third equation of motion

v^{2}=u^{2}-2 g h\\0 = 12\times 12 - 2 \times 9.8\times h\\h =7.35  m

Air having a pressure of 40 psig and a volume of 8 cu ft expands isothermally to a pressure of 10 psig. Find the external work p
DerKrebs [107]

Answer:

357.6 lb-ft

Explanation:

V = Volume = 8 ft³

dP = Change in pressure = (40-10) = 30 psig

Work done is given by

W=VdP\\\Rightarrow W=8\times (40-10)\\\Rightarrow W=240\ psig.ft^3

30\ psig=44.7\ psi\\\Rightarrow 1\ psi=\dfrac{30}{44.7}

So, converting to ft-lb

\dfrac{240}{\dfrac{30}{44.7}}=357.6\ lb-ft

The external work performed during the expansion is 357.6 lb-ft
