Objective: is to obtain the value of flexural stiffness (EI) of a given beam .
APPARATUS USED:
1) a rigid wooden or metal strip of uniform cross section
2) table fitted with end-supports
3) weight hangers and standard weight
4) measuring tape ( with metric graduation)
5) straight edge, ruler and pencil.
Procedure
Set the beam on two support to have two equal over hang then subject the free end to two concentrate loads of equal weight then deflection will occur upwards which bring about a shape called the definition shape also place the straight edge along the neutral axis of the beam before deflection then use ruler and pencil to work out the value
This course introduce the student to the basics of strength of materials. Topics include: loading statically indeterminate structure. Structure temperature and prestrain effect, shear force and bending moment, axial, shear bearing and bending stress, deflection of beam buckling of columns.the student will also learn how to determine the moment required to produce a given rotation .(rotational stiffness) at one end of the beam when the other side is pinned or fixed by using the required apparatus to carry out the experiment. And the subject matter has been arranged in such a manner that each chapter deal with the definition analysis of problem involved, derivations and application and the knowledge of these streets is essential to the safe design of a machine , aricraft, or any type of structure and most practical structure consist of complex arrangements of many components members. The students will be able to list a symbol , like length, breath, diameter, Dept, length, mass, modular ratio, pressure, radius, distance, thickness, uniformly distributed load, coordinate, area, constant points, complementary energy daimeter, young modulus , shearing force modulus of rigidity , force , second moment of area polar moment of inertia of area , bulk modulus, length , bending moment , radius, torque, strain energy , volume, total weight, coordinate, section modulus
