An 02-series single-row deep-groove ball bearing with a 65-mm bore (see tables 11–1 and 11–2 for specifications) is loaded with a 3-kn axial load and a 7-kn radial load. the outer ring rotates at 500 rev/min. (a) determine the equivalent radial load that will be experienced by this particular bearing. (b) determine whether this bearing should be expected to carry this load with a 95 percent reliability for 10 kh.

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
