Assume that if the shear stress in steel exceeds about 4.00 108 n/m2, the steel ruptures. (a) determine the shearing force necessary to shear a steel bolt 1.50 cm in diameter. n (b) determine the shearing force necessary to punch a 1.50-cm-diameter hole in a steel plate 0.640 cm thick. n

pe = weightxheight = 2000x1000=2,000,000joules

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
