SYNOPSIS

JJ310-STRENGTH OF MATERIALS

Provides knowledge on concepts and calculation of forces on materials, thermal stress, shear force and bending moment, bending stress, shear stress and torsion in shafts.

LEARNING OUTCOMES

Upon completion of this course, students should be able to:-

1. describe clearly forces on materials according to Hooke’s Law , shear stress and shear strain.

2. determine correctly thermal stress in series and parallel composite bars.

3. solve problems correctly in shear force and bending moment to the beam subjected to concentrated load and uniformly distributed load.

4. determine correctly bending stress for cantilever beam and simply supported beam.

5. use double integration method to solve successfully the deflection in the beam subjected to load and torsion for series and parallel composite shaft

CONTENT

1.0  FORCES ON MATERIALS
Analyze the effects of forces on materials, Hooke’s law, shear stress and shear strain.
2.0  THERMAL STRESSES AND COMPOSITE BARS
Explain thermal stresses and composite bars. Analyze on thermal stress for series and parallel composite bars subjected to external load and temperature changes.
3.0  SHEAR FORCES AND BENDING MOMENTS
This topic explains the types of beams and load. It also involves the law of equilibrium to determine the reaction forces. Explain the methods for drawing shear force diagrams, bending moment diagrams and the point of contraflexure.
4.0  BENDING STRESSES
This topic explains the standard symbols for bending stresses. It also involves the position of neutral axis and second moment of area to standard cross section of simply supported beam and cantilever beam.
5.0  BEAM DEFLECTION
This topic explains the deflection in the beam subjected to load and the calculation of beam deflection. Determine the deflection and slope at every specify points on simply support and cantilever beam by using double integration method.
6.0  TORSION
This topic explains the second polar moment of area for the round solid shafts and hollow shafts. It also deals with the maximum shear stress and angle of twist subjected to torque and solve problems on the power transmitted by the shaft, simple parallel and series composite shaft
