1ans) Four main kinds of soil behaviour

a) Elastic behaviour : A soil is said to be elastic when there is a change of shape or volume os soil when the load is applied and after the load is removed it regains back to the initial positioin after repeated no of loads.The stresses in the soil should not exceed the yeild stress.Peat comes to this category.

b) Plastic behaviour : A soil is said to be plastic when the property of the material to be deformed repeadly without repture by action of a force and remain deformed after removal of load.

c) Viscous behaviour: Viscous behaviour like creep,relaxation and rate dependent and these viscous effects occurs when the soil is consolidated or lightly consolidated.

d) Brittle behaviour: A Brittle behaviour of the soil occurs when the combination of specific volume,spherical pressure and deviatoric stress a soil will continue to deform at constant stress when sheared without any change in volume.

For a bronze alloy, the stress at which plastic deformation begins is 300 MPa and the modulus of elasticity is 115 GPa. What is the maximum load (in kN) that may be applied to a specimen having a cross-sectional area of 70 mm2 without plastic deformation? And if the original specimen length is 100 mm, what is the maximum length (in mm) to which it may be stretched without causing plastic deformation?

Two tennis balls undergo a head-on elastic collision. Under which of these initial conditions is it impossible for both balls to be moving in the same direction after the collision? (a) he lighter ball is stationary and the heavier ball is in motion. (b) he two balls have the same mass and are initially moving in the same direction, and they collide because the faster-moving ball overtakes the slower-moving one. (c) he two balls have the same mass and only...
