When a rod of circular cross-section is fixed at one end and subjected to an axial load of 500 N, the deflection under the load is found to be 2.4 mm, what will be the amount of deflection under the same load if the dia of rod is doubled & length is reduced to half of the original length?

• A. 1.2 mm
• B. 0.6 mm
• C. 0.3 mm
• D. 0.15 mm
