Axial Stresses and Strains
In the figure below the beam A-B-C is rigid and
is originally installed exactly horizontally.
Then the load P is applied.
The points at which the rods 1 and 2 are mounted at the
ceiling are immobile.
- After sketching the Free Body Diagram and obtaining the equilibrium
inspect your equations. Is this problem statically determinate or
By how much does the vertical position of point C change due to the
load P ?
NOTE : The angle between beam ABC and the horizontal will be only a few
degrees leaving the horizontal distance between the points A, B, and C
For both cables :|
Length L = 4 m;     Cross-section A = 5 cm2
Modulus of elasticity E = 200 GPa
Horizontal distances :
a = 3 m , b = 5 m
Load P = 60 kN
