1. The problem statement, all variables and given/known data

Determine support reactions.
a=3 m
b=2 m
c=3 m
F1=20 kN
F2=30 kN
F3=15 kN
M1=30 kN*m
M2=25 kN*m
M3=25 KN*m
q1=12 kN/m
q2=24 kN/m

2. Relevant equations

3. The attempt at a solution

Instead of posting a phone book worth of problems, why don't you pick one and concentrate on how to solve it?

Also, you should make an attempt at providing a solution before you post.

I'm Sorry, i think Number 17 and i just can't figure the solution out

Well, can you simplify the problem by figuring out some equivalent loads to substitute for the part loaded by q2?

After that, try writing the equations of static equilibrium for this frame.

Please can you give me some example, because i was in Informatique and i changed my Master

Maybe Problem 17 is a tad advanced for you, right now. Have you tried working any of the other problems on the page?

not really, i just want something to begin with. i'm new to physics now is like i'm in college

I would recommend that you start with a simpler problem, say No. 9.

Ok, can you teach me how to find the solution

Unfortunately, no. PF is not set up as a tutoring service.

I would recommend that you try to review your text or notes and make an attempt to solve this problem yourself. If you get stuck, you can post your work and ask for help or clarification.

In all such problems, draw a free body diagram for the beam and write the equations of static equilibrium.
