Identify the support reactions on the beam shown in $($Figure $1).$ AA is a fixed support.

Check all the possible support reactions on the beam, even if some of them are equal to zero due to the

loading given. Make sure the reactions in the set you choose do not depend on each other.

Identify the support reactions on the linkage shown in $($Figure $2).$

Check all the possible support reactions on the linkage, even if some of them are equal to zero due to the

loading given. Make sure the reactions in the set you choose do not depend on each other.

Identify the support reactions on the frame shown in $($Figure $3).AA$ is a roller and $BB$ is a pin.

Check all the possible support reactions on the frame, even if some of them are equal to zero due to the

loading given. Make sure the reactions in the set you choose do not depend on each other.

Identify the support reactions on the beam shown in $($Figure $4).$ The beam is supported by the roller BB and the

rocker $CC$ and contacts the smooth plane at AA$.$

Check all the possible support reactions on the beam, even if some of them are equal to zero due to the

loading given. Make sure the reactions in the set you choose do not depend on each other.
