A cantilever beam ABC is loaded as shown in Figure 1. A is a fixed support. Assume E= 200 GPa and I = 200 x 10^6 mm^4.
(a) Using the moment area method, determine the slope at B.
(b) Using the conjugate beam method, determine the vertical deflection at B.
(c) Using the virtual work method, determine the vertical deflection at C.
Compute for the stresses (initial, const and final stage)
and check for compliance in NSCP provisions.
Also compute the following:
1. Compute and check if the section is Uncracked,
Transition or Cracked as per NSCP.
2. Compute for its flexural capacity and check if it
could carry the given load.
