Question $19$

Using equilibrium and compatibility solve the below equations

The structural system in Figure $1$ below consists of a rigid bar supported by three cables $(E=24$

$k\frac{N}{m}m2).$ The bar carries a single$-$point load of $300$ N in addition to a self$-$weight of $480$ N $.$ The

cross$-$sectional area of each cable is $8$ mm $2.$ Calculate the displacements at b and f and

calculate the forces in the cables. All dimensions on the sketch are in mm $.$ Show all workings.
