Applied Mechanics and Graphic Statics A string of length 90 cm is fastened to two points ‘A’ and ‘B’ at the same level 60 cm apart. A ring weighing 120 g is slided on the string. A horizontal force ‘P’ is applied to the ring such that it is in equilibrium vertically below ‘B’. The value of ‘P’ is: 80 g 60 g 100 g 40 g 80 g 60 g 100 g 40 g ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The following is not a law of static friction: The force of friction depends upon the roughness of the surface The force of friction always acts in a direction opposite to that in which the body tends to move The force of friction is dependent upon the area of contact The magnitude of the limiting friction bears a constant ratio to the normal reaction between two surfaces The force of friction depends upon the roughness of the surface The force of friction always acts in a direction opposite to that in which the body tends to move The force of friction is dependent upon the area of contact The magnitude of the limiting friction bears a constant ratio to the normal reaction between two surfaces ANSWER DOWNLOAD EXAMIANS APP
