A closed-coil helical spring is to have stiffness of 900 N/m in compression with a maximum load of 45 N and a maximum shearing stress of 120 N/mm2. The length of the spring is 45 mm. find the ...Read more
Determine the crippling load for the “T”section of length 5m when it is used as a strut with both ends hinged. E=2.0x105N/mm².
At a point in an elastic material under strain, the stresses on the three mutually perpendicular planes are as follows: A normal tensile stress of 60 N/mm2 and shear stress of 40 N/mm2 on one plane and a normal ...Read more
Compare the flexural strength of the following three beams of same material having equal weight and equal length. a. I-section 30cm x15 cm, having 2 cm thick flanges and 1.25 cm thick web b. Rectangular section having depth ...Read more
What is the ratio of the strength of a solid steel column of 150 mm diameter to that of a hollow circular steel column of the same cross-sectional area and a wall thickness of 15 mm? The two ...Read more
