Part a: Solve for the forces in the cables AB and BC in terms of the weight of the hanging mass.

Part b: Solve for the forces in the cables AB and BC in terms of the weight of the hanging mass.

Part c: Find the maximum mass that can be supported. $($The answer should be in kg$)$

Two high$-$strength steel rods of different diameters are attached to points A and $C$ and support a

mass $M$ at point $B,$ as shown in Figure $3\mathrm{.}1.$ The ultimate strength, i$.$e$.,$ the stress at which fractur

occurs, of the two rods is ${}_{\text{u}\text{l}\text{t}\text{.}}$ Rod $AB$ has a cross sectional area of $A_{AB}$ and rod $BC$ has a cros

ectional area of $A_{BC}.$ What is the maximum mass $M$ that can be supported?

Take $A_{AB}=200m{m}^2$ and $A_{BC}=$

$350m{m}^2$

Take ${}_{\text{u}\text{l}\text{t}}=300$MPa,$a=275$

mm$.$
