1. What is creep?
Is the term used to desribe the tendency of a material to move or to deform permanently under a
constant load over a period of time to relieve stress
2. Mention at least 3 factors which affect rate of creep
1. Mention atleast three methods by which fracture occurs
Slow application of external loads
Rapid application of external loads
Cyclic or repeated loading
Time dependent deformation under constant load
2. What is fatigue? How does it occur?
Fatigue is th
The phenomenon of failure of a material under cyclic loading known as fatigue is estimated to be
the cause of ninety percent of all metal failures. Fatigue failure is caused by applied stress of a
sufficient magnitude, large variation or flu
Heat Treatment is a procedure in which heat or cooling is applied to metals to alter their
physical and mechanical properties without changing the shape. Heat treatment can be used to
restore ductility to a metal, improve machining, improve
what is heat treatment?
Heat treatment is the controlled heating and cooling of metals to alter their physical and
mechanical properties without changing the product shape.
mention the general steps in heat treatment process
3 basic steps
Heat metal to sp
1. What are plastics? Give an example
Plastics are synthetic organic polymers capable of being molded or formed used in different
applications. Example : PVC, Epoxy, ABS
2. Define Homopolymer, Heteropolymer, and teropolymer

Unique Design for Go-Cart Frame Using Composite Materials
After analysis of the materials stress and strain calculations, we have decided to forgo our
initial usage of a composite carbon fiber for the frame.
The composite carbon fibe
