a ductile hot-rolled steel bar has a minimum yield strength in tension and compression of 350 mpa. using the distortion-energy and maximum-shear-stress theories, determine the factors of safety for the following plane stress states.

b.a device that inputs heat into a cool object

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
