Problem $1$

A frame ABCD is supported by a roller at point D and by a pin at point A $.$ The structure is

subjected to point loads, shown in Figure $1\mathrm{.}1.$

Calculate the internal loadings $($normal and shear forces, bending moment$)$ at the cross sections

through points $G$ and $H$ using the method of sections.

For cuts on vertical structural

members, please use the

following senses as the

positive sign convention for

internal reactions:

Question $8$

For problem $1,$

Part h: Find the internal shear force reaction $V_H$ at cross$-$section H $($answer should be in

kN $)$

Note: For internal reactions, the positive$/$negative should follow the convention defined in

the lecture.

Question $9$

For problem $1,$

Part i: Find the internal bending moment reaction $M_H$ at cross$-$section H $($answer should be

in kN m $)$

Note: For internal reactions, the positive$/$negative should follow the convention defined in

the lecture.
