Q$2$:

DETAIL C

SECTION $1-1$

SECTION BC and AB

$P=10+x+2y+5z[kN]$

$P=34$

For the system given in the figure, if the

load is acting at point $B$;

a$)$ Check the safety of the bars $BC$ and $AB.$

Note that the cross sections of the bars

are identical.

b$)$ Calculate change in lengths of $BC$ and

$AB$ bars $?,L_{AB}=?)$ and determine

the displacement of point $B.$

c$)$ Based on the connection detail at point

$C($Detail $C$ and section $1-1),$ determine

appropriate pin diameter to transfer

the shear force safely.

For the bars:

${}_{a||}=14k\frac{N}{c}{m}^2,E=21000k\frac{N}{c}{m}^2$

For the pin:

${}_a=14k\frac{N}{c}{m}^2$
