To Find out the Reaction of Simply Supported Beam
Apparatus:
Spring balance, Stands, Leveling deices, weights and hangers.
Principle:
- Condition of equilibrium for vertical parallel forces acting on a body is
- Sum of all the force s should be zero.
- It should satisfy the principle of moments .
- If we take moment about a point on moments should be equal to anti clockwise moments.
Procedure:
-
Set the apparatus accordingly
-
Then hang the beam on the hooks and weights on bam with hangers.
-
Note the distance of weight jaws from the support and value of weights.
-
Using the two condition of equilibrium calculates R1 & R2.
-
For this one should know values o weight of beams, length of beams and weight of hanger
Observation and Calculations
Weight of hanger = 0.1 lb
Weight of rod W3 = 5.84 lb
Length b/w the supports = 42 in
| W1 | W2 | L1 | L1/ | L2 | L2/ | RA | RB |
| 0.6 lb | 0.6 lb | 10 in | 32 in | 32 in | 10 in | 3.5 lb | 3.5 lb |
| 0.85 lb | 0.6 lb | 7 in | 35 in | 24 in | 18 in | 3.85 lb | 3.74 lb |
| 0.6 lb | 0.8 lb | 24 in | 18 in | 7 in | 35 in | 3.72 lb | 3.88 lb |
