A 0.2 mm thick tape goes over a frictionless pulley of 25 mm diameter. If E of the material is 100 GPa, then the maximum stress induced in the tape is
A cantilever beam of rectangular cross-section is 1 m deep and 0.6 m thick. If the beam were to be 0.6 m deep and 1 m thick then the beam would
The product El is known as
The assumption “the plane section before bending remains plane after bending” made in the theory of bending implies:
At the neutral axis of simply beam, there is
where y is the distance of any fibre from the neutral axis.
For the neutral axis, y = 0, ∴ σ = 0
For a beam of uniform strength, if its depth is kept constant, then its width will vary in proportion to
for beam of uniform strength, σ = constant at any section
so, M α Z
∴ M α width
When a rectangular beam is loaded longitudinal, shear develops on
A beam is said to be of uniform strength, if
A rod of length L and diameter D is subjected to a tensile load P. Which of the following is sufficient to calculate the resulting change in diameter?
Beams of uniform strength so vary in section that the
Unit stress means stress at any section.
