Question

The frame has dimensions H1 = 4 m , H2 = 3 m , and L1 = 6 m , and supports two lateral loads P1 = 10 kN and P2 = 12 kN . The area of column AE is 40 cm2 and the area of column BF is 80 cm2 .

Gy = 13.3 kN

Ax = 11.0 kN

a) What is the horizontal reaction from the ground on the base of the column at B? Let a positive reaction be pointing to the left.

Bx = ?

 

Review
What is the horizontal reaction from the ground on the base of the column at B? Let a positive reaction be pointing to the left.
Express your answer with the appropriate units to three significant figures.
View Available Hint(s)
- Hint 1. How to approach the problem
Once the elements in the first column have been analyzed, the free-body diagrams of the pieces KFL , LHDI , and IB can solved from the top down.
Hint 2. Find the horizontal reaction at L
Use the sum of the moments about K to find the horizontal reaction at L. Recall that Ly = 3.00 kN , H2 = 3 m , and Li = 6 m .
