For a bronze alloy, the stress at which plastic deformation begins is 294 mpa and the modulus of elasticity is 121 gpa. (a) what is the maximum load that can be applied to a specimen having a cross-sectional area of 327 mm2 without plastic deformation? (b) if the original specimen length is 129 mm, what is the maximum length to which it may be stretched without causing plastic deformation?

Asled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slidesa distance d1 down the slope and then covers the distance d2 alongthe horizontal terrain before stopping. find the coefficient ofkinetic friction μk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionμk. express your answer in terms of someor all of the variables d1, d2, and θ.

Four identical lab carts each have a mass of 200 kg. different masses are added to the carts and the velocities are measured. all carts move to the right.

Global climatic patterns are changing because of the melting of polar ice caps. the melting of polar ice caps is an example of the interaction between the atmosphere and cryosphere cryosphere and geosphere hydrosphere and geosphere biosphere and cryosphere
