GATE 2023 Strength of Materials-2 Quiz 7

I section of a beam is formed by gluing wooden planks as shown in the figure below. If this beam transmits a constant vertical shear force of 4000 N, the glue at any of the four joints will be subjected to a shear force of ____ kN per meter length.

A bar AB of length 8m and diameter 100mm is fixed rigidity. Torque 1000 N-m applied at 3m from A. The fixing couple at A and B are

When a column is subjected to an eccentric loading then the type/s of stress which come/s into place are

(a) Direct stress

(b) Bending stress

If (80,20) and (60,40) N/mm² are any two point on Mohr circle, then calculate the maximum shearing stress in N/mm². (round off to two decimal places)

At a point in a material subject to two dimensional stress, the stress on as certain plane are  and on another plane the stresses are  and  as shown in the figure

Which of the following is/are correct? (Assume )

A simply supported beam of span 10 m carries a udl of 1152 N/m over the entire span. The beam is propped at the middle of the span. Then the amount, by which the prop should yield (in mm), in order to make all the three reactions equal will be_____mm. (Round off to one decimal place) (Take E = 2 × 10⁵N/mm² and ‘I’ for beam = 10⁸ mm⁴)

A propped cantilever is supported by the mid span of simply supported beam of same length at propped end. If the propped cantilever is loaded with udl of 17 kN/m and span length of both beam is 5 m. Calculate the reaction generated at propped end.
