The tractor is used to lift the 160-kg load b with the 24-m-long rope, boom, and pulley system. the tractor travels to the right with an acceleration of 2 m/s2 and has a velocity of 4 m/s at the instant sa = 5 m. when sa = 0, sb = 0. express your answer to three significant figures and include the appropriate units.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
