Answer:
A 200mm lever and a 240 mm diameter pulley are welded to the axle BE that is supported by bearings at C and D. If a 860N vertical load is applied at A when the lever is horizontal, determine (a)the tension in the cord, (b)the reactions at C and D. assume that the bearing at D does not exert axial thrust.
see explanation
Explanation:
Part a
The tension in the cord

860(200) - T(120) = 0
T(120) = 172000
T =1433.33N
The tension in the cord (T) = 1433.33N
Part b
Apply the moment law of equilibrium at point D about y-axis.


sustitute 1433.33N for T

The reaction at C along x-axis 477.78N
Apply the moment law of equilibrium at point D about x-axis


The reaction at C along y-axis is 143.33N
Apply the force law of equilibrium along z direction.


The reaction at C along z-axis is 0N
Apply the force law of equilibrium along x direction.


substitute 477.78N for
and 143.33N for 

The reaction at D along x-axis is -1911.11 N
Apply the force law of equilibrium along y direction.


substitute 1433.33 for 

Answer:
then why do you ask?
Explanation:
lol anyways thanks for the points
An atom is the smallest unit of matter. It can't be broken. It consist of dense nuleus surrounded by negatively charged electrons.
<span>The correct answer is B. Inverted image. This is because of all the lenses and light refractions and what not. The same things happens with our eyes except our brains fix the inverted image automatically. Since there are no brains in a projector, you have to fix it on your own by putting it in reverse.</span>
