Micro structure can be used to reduce friction and slipping of a smooth surface becoming possible to hold on.
<u>Explanation:</u>
Micro structure is a structure which is very fine and small. It can be made visible if it is seen with the help if a micro scope. It can not be seen other wise directly through the eyes because it is very small is size not becoming visible to the eyes.
These even though are very small is size can be helped to increase the friction on a smooth surface and reduce the slipping of the object off the smooth surface. This will lead to no hurting of the person off a smooth surface.
Answer:
Steam Engine
Explanation:
It stopped being produced due to other types of engines being much more efficient.
Answer:
hello your question is incomplete below is the missing part of the question and attached is the missing diagram
In the simply-supported beam shown in the figure below, d1=14 ft, d2=7 ft, and F=15 kips. so find Az, Ay, By.(in kips)
answer :
Reaction force at B = 10 kips
Reaction force in the y axis = 5 kips
Reaction force in the Z direction = 0 kips
Explanation:
Taking moment about point A
∑ Ma = 0
By + ( d1 + d2 ) - F*d1 = 0
By ( reaction force at B ) = ( 15 * 14 ) / ( 21 ) = 10 kips
Applying equilibrium forces in the Y-axis
∑ Fy = 0
Ay - F + By = 0
where : F = 15, By = 10
hence ; Ay = 5 kips
applying equilibrium forces in the Z-direction
∑ Fz = 0
Az = 0 kips
