TITLE OF EXPERIMENT:

REACTIONS OF SIMPLY SUPPORTED BEAMS

DATE PERFORMED:

13TH OF AUGUST 2008.

AIM:

I) TO DETERMINE THE REACTIONS RA AND RB FOR A BEAM SIMPLY SUPPORTED AT ITS ENDS

II) TO DETERMINE THE VALUES OF RA AND RB AS A GIVEN LOAD MOVES FROM ONE END OF A SIMPLY SUPPORTED BEAM TO THE OTHER

APPARATUS:

• Two spring balances. • A steel beam of hollow section. • Load hanger. • Load / weights ranging from 2kg to 10kg. • Meter rule. • Inextensible cord.

THEORY
A beam with a constant height and width is said to be prismatic. When a beam’s width or
A load hanger was placed at the mid-point of the beam of given span, and the spring balances read. The 2kg weight was placed on the hanger and the deflection in the spring balances read. The load was increased in steps of 2kg up to 16kg and the balances read in each case (i.e. at each incremental loading. All weights were then removed.

Next, the load hanger weight was placed directly under the spring balance A and the two spring balances read. A 8kg weight was put on the load – hanger and the spring balances read. It was then (i.e. the load) was then put (transferred) to the next 100mm.

rate of a reaction by lowering the activation energy of the reaction. Chemists discovered catalysts when they were trying to determine how to turn one substance into another. Although early chemists did not resolve how to turn substances into one another, they did discover that various materials could be changed from one form to another. This also led to the discovery that if certain chemicals were present in the reaction, the change would occur faster without consuming itself in the reaction. It is…

was supported as the rate of reaction did increase as the concentration and the temperature increased. The concentration, or molarity, of the reactants increased in relation to time in the form M=1.1541e0.0016t. This is an accurate relationship as the volume remains the same as the number of molecules increase, thus the rate would increase exponentially as the molecules collide at a constant growth rate. This is also a reliable model as the R² value is 0.9697. The hypothesis that the reaction would…

Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. Chemical reactions vary greatly in the speed at which they occur. Some are essentially instantaneous, while others may take a very long time to reach equilibrium. The reaction is presented by The time in the reaction when the mixture remains colourless is the clock period. This will depend upon the initial concentrations of the sodium bisulphite ions (NaHSO3) and the potassium iodate ions (KIO3)…

Fig. 2(A) shows the CV curves, indicating the tendency and relation of current with varying potential (volt). As the hydrolysate dilution was increased, the maximum current density decreased. CV is widely used to obtain the voltammetry data. The cyclic voltamograms provides the information of the redox reaction and adsorption/desorption…
