Two 0.5 cm-diameter rods of 1020 steel (σts = 395 mpa) are to be joined with a silver braze alloy 0.025 cm thick (σys = 145 mpa) to produce one long rod. the ultimate strength of this brazed structure is found to be approximately 345 mpa. if it is necessary to reduce the diameter of the rods to 0.25 cm with no change to the braze joint itself, will the strength (in mpa units) increase, decrease, or remain the same? if it changes, by how much?

On a average work day more than work place firs are reorted

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.
