A temporary diversion has been constructed on a highway of +4 percent gradient due to major repairs that are being undertaken on a bridge. The maximum speed allowed on the diversion is 10 mph. Determine the minimum distance from the diversion that a road sign should be located informing drivers of the temporary change on the highway.
- Maximum allowable speed on highway = 70 mph
- Letter height of road sign = 4 in.
- Perception-reaction time = 2.5 sec
Assume that a driver can read a road sign within his or her area of vision at a distance of 40 ft for each inch of letter height.
a wheel rolls to the right with an angular velocity of 2 rad/s while slowing down at a rate of 3 rad/s^2. knowing the wheel rolls without sliding and ignoring the effect of gravity determine the location on the wheel where the net acceleration is ..
A stopwatch was started when h was 501 mm and read 17.6 seconds when h was 244 mm; the test was repeated for a drop from 254 mm to 97 mm and the time was 22.4 seconds.
