For a bronze alloy, the stress at which plastic deformation begins is 267 mpa and the modulus of elasticity is 115 gpa.
(a) what is the maximum load (in n) that may be applied to a specimen having a cross-sectional area of 341 mm2 without plastic deformation? in (n)
(b) if the original specimen length is 169 mm, what is the maximum length (in mm) to which it may be stretched without causing plastic deformation? in mm

Which statement best describes copper? a. it has a low resistance and prevents charges from moving freely. b it has a high resistance and allows charges to move freely. c. it has a high resistance and prevents charges from moving freely. d. it has a low resistance and allows charges to move freely

In an experiment, how can i change human errors? be specific.

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
