A steel plate, connected to a fixed Channel using three identical bolts A, B and C, carries a load of 6 kN as shown in the figure. Considering the effect of direct load and moment, the magnitude of resultant shear force (in kN) on bolt C is
-
- 13
- 15
- 17
- 30
Correct Option: C
Pp = | = | = 2 kN. | ||
n | 3 |
rA = rC = 50, (PS)A = (PS)C
rB = 0 ⇒ (PS)B = 0
(PS)C = | [rC2 + rB2 + rA2] = P × e | rC |
(PS)C × 2 × rC = P × e
(PS)C = | = 15 KN | 2 × 50 |
QA = 180°, QC = 0°
Resultant shear force (RC) = PP + (PS) C.
RC = 2 + 15 = 17 KN
