Problem $5$

The shown frame is made up of two links

connected by a hinge at $B.$ The frame is

loaded by a horizontal force $P=2kN$ acting

at the middle of the member $AB$ and

supported to the ground by hinges at A & C

as shown. Determine the forces at the joints

A$,$ B$,$ &C$.$

Problem $6$

For the frame and loading shown,

determine the components of all the

forces acting at all the pins B$,$ C$,$ & D$.$

Take $P=15kN$

Problem $7$

Determine the force in each member of the space

truss and state if the members are in tension or

compression. Hint: The support reaction at E

acts along member EB$.$ Why?

Problem $8$

The shown $3$ dimension truss is supported by a ball

and socket joint at D$,$ and two short members at A$,$ &

$B,$ and as shown. For $P=4kN,$ determine

i$-$ the reactions at the supports

ii$-$ the force in each member
