A triangular distributed load of max intensity w = 420 N/m acts on beam A B . The beam is supported by a pin at A and member C D , which is connected by pins at C and D respectively. Determine the reaction forces at A and C . Enter your answers in Cartesian components. Assume the masses of both beam A B and member C D are negligible.

hello your question is incomplete attached below is the missing diagram

a = 5.20 m

b = 7.80 m

c = 4.16 m

answer :

Reaction force at A :

= Fax i  + Fay j

=  -14836.5 i  - 9139.2 j   N

Reaction force at B

= Fcx i + Fcy j

= - 14836.5 i - 11869.2 j   N

Explanation:

attached below is the detailed solution

Reaction force at A :

= Fax i  + Fay j

=  -14836.5 i  - 9139.2 j   N

Reaction force at B

= Fcx i + Fcy j

= - 14836.5 i - 11869.2 j   N

d would be the most obvious choice to this question. leaders are supposed to herd their underlings like a shepherd to sheep. a leader should also listen to others when they are talking to one other to gain a better understanding of their mission and surroundings.
