Video Solution
Question 43

Two planks each of $$50mm \times 50 mm $$ section are glued together along the length to form a section 50mm \times 100 mm and used as a beam .If the shear force at a section is 1000 N ,What is the maximum shear stress on the glue ?

Video Solution
Question 44

At certain point in a structural member , there are perpendicular stresses 80 $$\frac{N}{mm^{2}}$$ and 20 $$\frac{N}{mm^{2}}$$,both tensile .what is the equivalent stress in simple tension ,according to the maximum principal strain theory ?(poisson's ratio=0.25)

Video Solution
Question 45

Two simply supported beams are made up of the same material and are of the same cross section .Both beams carry uniformly distributed loads of equal intensities .one of the beam is 2 m long and the other is 4 m long . The 2 m long beam shows a central deflection of 1mm.what is the central deflection of the 4m long beam?
