The free-body diagram of the beam which supports the 80-kg load and is supported by the pin at A can be seen in the image attached below.
The first image shows the diagram of the beam and the second image shows the free-body diagram of the beam.
The resolution of forces in the system is well understood by the principle of equilibrium where a stationary body will remain balanced when subject to parallel forces provided that the total sum of the overall external forces is zero.
The free-body diagram is a graphical representation used to visualize the forces applied to an object.
The equilibrium of forces on the x-axis is:
The equilibrium of forces on the y-axis is:
The equilibrium condition at any point is:
From the free body diagram attached in the second image below,
- the horizontal reaction is located at point A as
- the vertical reaction is located at point A as
- the tension = T
- the weight = W
Therefore, we can conclude that the free-body diagram of the beam which supports the 80-kg load and is supported by the pin at A can be seen in the image attached below.

Answer:
1) <em>4.41 * 10^-4 kw </em>
<em>2) </em>2.20 * 10^-4 kw
Explanation:
Given data:
Filter = 500 m^3/min
dust velocity = 3g/m^3
bag ; length = 3 m , diameter = 0.13 m
change in pressure = 1 kPa
efficiency = 60%
<u>1) Calculate the Fan power </u>
First :
Calculate the total dust loading = 3 * 500 = 1500 g
To determine the Fan power we will apply the relation
=
<em>fan power ( </em> )<em> = 4.41 * 10^-4 kw </em>
<u>2) calculate power drawn </u>
change in P = 6 atm = 6 * 10^5 pa
efficiency compressor = 50%
hence power drawn = 4.41 * 10^-4 kw * 50% = 2.20 * 10^-4 kw
