Question

A truss is subjected to three loads. The truss is supported by a roller at A and by a pin joint at B. What is most nearly the reaction force at B

Answer 1

Answer:

Hello the diagram related to the question is missing attached is the diagram

Answer : 3833.33 KN

Explanation:

The most nearly reaction force at B

= ∑ Mb = 0 = 21Ay

= (2000 * 17.5 ) + ( 3000 * 10.5 ) + ( 4000 * 3.5 )

= 35000 + 31500 + 14000 = 80500

therefore Ay = 80500 / 21 = 3833.33 KN

x = 7/2 = 3.5m
