There are totally 4 questions .i struggled for a whole day and i still cannot solve it.Please help me!(adsbygoogle = window.adsbygoogle || []).push({});

For Question 1:

My problem is that i cannot find out the reaction Ax,Ay,Dx,Dy though i establish 4 eqt:

1:Ax+Dx=90 kN

2:Ay+Dy=90 kN

3:summation Ma=0 ,anticlockwise positve

-125+2Dx+5Dy=0

4:summation Md=0 ,anticlockwise +ve

505-2Ax-5Ay=0

For Question 2:

i dunno what is the meaning of G=80kN/mm^2 and how to calculate the shear force?

also, what is Bredt-Batho theory? My professor haven't mentioned it so far.

For Question 4:

The first load from left P=WL/5 is outside the Y-axis, does it mean that i can neglect it?

to find the equation of elastic curve, do i need to establish the Moment equation for each section?
