The benefit of having a eutectic point for ferrous alloys used for casting needs to be explained. Concept Introduction: Ferrous Alloys- The cast iron is brittle in nature because of the presence of iron carbides. Ferrous alloys are also called as cast iron because these are generally manufactured from casting. The major part of engineering application of ferrous alloys is Steel. Cast iron is mostly used as a structural component. These are used in automobile industry of motor casing, machinery's sliding guides, lathe bed etc. Classification −Based on the carbon content present: Steel: In steel, the carbon percentage is 2 .14% Cast iron: Carbon percentage is above 2 .14%

Question

3–16. A particle of mass m is embedded at a distance R from the center of a massless circular disk of radius R which can roll without slipping on the inside surface of a fixed circular cylinder of radius 3R. The disk is released with zero velocity from the position shown and rolls because of gravity, all motion taking place in the same vertical plane. Find: (a) the maximum velocity of the particle during the resulting motion; (b) the reaction force acting on the disk at the point of contact when it is at its lowest position.

Concept Introduction:

Ferrous Alloys-

The cast iron is brittle in nature because of the presence of iron carbides. Ferrous alloys are also called as cast iron because these are generally manufactured from casting.

The major part of engineering application of ferrous alloys is Steel. Cast iron is mostly used as a structural component. These are used in automobile industry of motor casing, machinery's sliding guides, lathe bed etc.

Classification −Based on the carbon content present:

Steel: In steel, the carbon percentage is 2.14%

Cast iron: Carbon percentage is above 2.14%

I have figured out the support reactions, Ay = 240 kN, Ax = 0 kN, Ma = 639.2 kN*m and the constant term for V(x) is 240. I am not figuring out the function of x part right. Show how to derive V(x) and M(x) for this distributed load.

2.4 (A). A 75 mm diameter compound bar is constructed by shrinking a circular brass bush onto the outside of a 50 mm diameter solid steel rod. If the compound bar is then subjected to an axial compressive load of 160 kN determine the load carried by the steel rod and the brass bush and the compressive stress set up in each material. For steel, E 210 GN/m²; for brass, E = 100 GN/m². [I. Struct. E.] [100.3, 59.7 kN; 51.1, 24.3 MN/m².]
