(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The question is:

The weightless beam, ABCD, shown in Figure below is supported by a pin support at B, and a roller bearing at C. There is a 4 kN/m UDL along the whole beam, as shown. There is an 11.2kNm clockwise couple at A.

The vertical reactions of B and C are:-

2. Relevant equations

Nothing really

3. The attempt at a solution

Now I'm assuming that since If I start from at B= 0 to find the vertical reaction of C

For the UDL, it would be 4 x (1.8+2+2.2) = 24

thus

[tex]\sum[/tex] Mb = 0 = 11.2kNm - Vc x 2 - 24 x 3

However, I keep on getting the incorrect answer with Vc. Usually I've been doing problems where the pin supports are at the ends of a beam.

Any help and tips would be appreciated for this type of problem
