This is an arch, its basically a half circle attach to a rectangle, you could also think of it as an upside down U. A dome is a Sphere with the inside hollowed out.
1 difference is a dome is a 3 dimensional shape while an arch is normally not. Or that a dome is the complete shape with a arch act as it’s diameter.
It can provide measurements of stars with a higher angular resolution than is possible with conventional telescopes.
Answer:
the relation between load , shear force and bending moment is
shear force in a beam is calculated by the differentiation of the loading with respect to distance or length of the beam

Bending moment in a beam is define as the change of shear force diagram with respect to the length of the beam.

and where as
where V is the shear force , x is the distance in the beam , M is the bending moment and w is the loading on the beam.
Answer:

Explanation:
Given data:
length of Steel bolt 
Length of aluminium cylinder 
Pitch of bolt p = 1mm
Modulus of elasticity of steel E = 215 GPa
Modulus of elasticity of aluminium = 74 GP
Area of bolt 
Area of cylinder = 2300 mm^2
n =1
By equilibrium



By the compatibility

Displacement in steel is 
Displacement in Aluminium is 
from compatibility equation we have



substitute




Stress in Aluminium
