A semicircular disc rests on a horizontal surface with its top flat surface horizontal and circular portion touching down. The coefficient of friction between semi circular disc and horizontal surface is µ. This disc is to be pulled by a horizontal force applied at one edge and it always remains horizontal. When the disc is about to start moving, its top horizontal force will
A semi-circular disc rests on a horizontal surface with its top flat surface horizontal and circular portion touching down. The coefficient of friction between semi-cricular disc and horizontal surface is i. This disc is to be pulled by a horizontal force applied at one edge and it always remains horizontal. When the disc is about to start moving, its top horizontal force will
A king ordered to make a crown from 8 kg of gold and 2 kg of silver. The goldsmith took away some amount of gold and replaced it by an equal amount of silver and the crown when made, weighted 10 kg. The king knows that under water gold loses \(\frac{1}{20}th\) of its weight, while silver loses \(\frac{1}{10}th\). When the crown was weighted under water, it was 9.25 kg. How much gold was stolen by the goldsmith?
Consider the following statements in respect of arched construction made of voussoirs: 1. The superimposed load is transferred to the sidewalls only by the strength of cohesion of the mortar between the voussoirs. 2. The arch may fail under crushing when the compressive stress or thrust in it exceeds the safe crushing strength of the voussoir material. 3. Every element in the arch is subjected to compression only. 4. Failure of the arch due to the sliding of any voussoir past the adjacent one due to transverse shear can be avoided by reducing the height of the voussoirs. Which of the above statements are correct?
The horizontal deflection of a parabolic curved beam of span 10 m and rise 3 m when loaded with a uniformly distributed load $$l$$ t per horizontal length, is (where $${I_{\text{c}}}$$ is the M.I. at the crown, which varies as the slope of the arch).
