Question

Show that in an inclined plane, angle of friction is equal to angle of repose

Answer 1

Answer:

The main difference between angle of friction and angle of repose is that the angle of friction is defined as the angle between the normal reaction force and the resultant force of normal reaction force and friction when an object just begins to move, whereas the angle of repose is defined as the minimum angle of an ..

Archimedes' principle is named after Archimedes of Syracuse, who first discovered this law in 212 BC.[4] For objects, floating and sunken, and in gases as well as liquids (i.e. a fluid), Archimedes' principle may be stated thus in terms of forces:

Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object

—with the clarifications that for a sunken object the volume of displaced fluid is the volume of the object, and for a floating object on a liquid, the weight of the displaced liquid is the weight of the object.[5]
