Direction: A triangular-shaped cantilever beam of uniformthickness is shown in the figure. The Young's modulus of the material of the beam is E. A concentrated load P is applied at the free end of the beam.
-
The area moment of inertia about the neutral axis of a cross-section at a distance x measured from the free end is
-
-
bxt³ 61 -
bxt³ 121 -
bxt³ 241
-
xt³ 121
-
Correct Option: B
At a distance of x from the free end width
| b' = | |
| l |
| ∴ Moment of Inertia Ix = | |
| 12l |
