Using the 25.4 mm x 6.35 mm x 1200 mm aluminium beam, set it up with an initial span of 745 mm between two load measuring piers and secures the beam clamps finger tight. (using Vernier calliper and Tap measure). Fix a load clamp at mid-span and add a load hanger. Set up a dial gauge over the clamp and set the distance of 400 mm from left support, with its anvil removed, to measure at least 12mm downward deflection. Zero the interface force channels. Depress the centre of the beam two or three times to minimise friction and re-zero if necessary. Add the load of 10N in the load hanger. Record the value of Dial gauge value as a deflection. Take the young’s modulus “E” =78 GPa for aluminium.
1.Using Macaulay’s method calculates the deflection at 0.2m from left side of support.
2.Compare the value between theoretical values and practical values.
3. Record the percentage of error with the theoretical values and Software simulated values.
4. Using Solidworks software, Simulate the Beam loading condition and Obtain stress, deflection and SFD&BMD.

(using Vernier calliper and Tap measure). Fix a load clamp at mid-span and add a load hanger. Set up a dial gauge over the clamp and set at the middle span of beam, with its anvil removed, to measure at least 12mm downward deflection. Zero the interface force channels. Depress the centre of the beam two or three times to minimise friction and re-zero if necessary. Add the load of 10N in the load hanger. Record the value of Dial gauge value as a deflection. Take the young’s modulus “E” =95 GPa for brass.
