shearing force (SF) at any section of a beam represents the tendency for the portion of the beam on one side of the section to slide or shear laterally relative to the other portion. The diagram shows a beam carrying loads . It is simply supported at two points where the reactions are Assume that the beam is divided into two parts by a section XX The resultant of the loads and reaction acting on the left of AA is F vertically upwards and since the whole beam is in equilibrium‚ the resultant force

reinforced concrete beam shown in Figure 1 carries an imposed live load of 12kN/m2 and a dead load of 12 kN/m2 as shown in the diagram. Given‚ fcu = 30 N/mm2‚ fy = 460 N/mm2‚ fy‚ links = 250 N/mm2. The beam is exposed to a mild condition. a) Determine whether the beam is singly or doubly reinforced beam. b) Determine the main reinforcement for the beam using a design chart. c) Determine the shear reinforcement for the beam. d) Check whether the deflection of the beam is acceptable.

3.4 Thermal Effect Shear strain In general‚ increase in temperature causes the atoms to vibrate more and makes average atomic spacing greater. Macroscopically‚ this will lead to dimension increase in solid: T + T +V T – T – V In an isotropic material‚ temperature change only introduces variation of direct (normal) strain. In other words‚ thermal deformation does not cause shear strain. where T0 is a reference temperature and = coefficient of thermal expansion (C)-1 Hooke’s

deflections of a beam are an engineering concern as they can create an unstable structure if they are large. People don’t want to work in a building in which the floor beams deflect an excessive amount‚ even though it may be in no danger of failing. Consequently‚ limits are often placed upon the allowable deflections of a beam‚ as well as upon the stresses. When loads are applied to a beam their originally straight axes become curved. Displacements from the initial axes are called bending or flexural

In this case‚ I had a few hypothesis and predictions on this experiment. First off‚ refraction is the bending of light when it travels through different medium. Therefore‚ the light will bend and it will shift away from the original location. However‚ I don’t know where the shift will be‚ but according to the research done on types of mirage‚ I believe that

buckling. There are several different types of buckling that can take place in objects and those are described as below. Flexural buckling is a special form of buckling that takes place in a special compression member facing a deflection because of the bending of flexure. It occurs mostly in a straight column when the stable equilibrium gets distorted at the critical load. The buckling is shown to occur mainly at the axis and demonstrates significantly small radius of gyration. There are different types
