Asteel rod 55 cm long has a diameter of 30 cm. the compressive strength (the maximum stress it can support without breaking) of this steel is 500 × 106 n/m2. what is the compression force that would break the rod?

in physics zero. in muscle fatigue could be high

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

the answer is 12 as i may remember

: )

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
