Bar (1) has a length of l1 = 2.50 m, and bar (2) has a length of l2 = 0.65 m. initially, there is a gap of d = 3.5 mm between the rigid plate at b and bar (2). after application of the loads p to the rigid plate at b, the rigid plate moved to the right, stretching bar (1) and compressing bar (2). the normal strain in bar (1) was measured as 2,740 μm/m after the loads p were applied. determine the normal strain produced in bar (2).

Explain how the energy of rubber ball is tranforned as it roll down a ramp. give evidence that the energy of the og the ball remains the same at all points on the ramp

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
