I have an interest in using or substituting 3/4“ 40 gauge grey colored electrical conduit for ?” white colored 40 gauge irrigation pipe, so that the pipe will blend in with fencing and because it is suppose to be more resistant to sunlight. Is it o.k. to do this and will the pipe work alright with the standard white irrigation fittings and the purple colored pvc glue?
There are some pretty major joints (and painful to heal) from your hips down (including lower spine, as the song says they are connected). Jeans offer no protection at all, even from abrasion, that does not stop me from wearing jeans on most occasions so it would be hypocritical of me to say don’t wear them, just be aware – however, I always wear boots that offer some support and protection to the ankles. Proper safety gear can minimise injuries, however even in the best conditions, say a race track (plenty of runoff, no 4 wheeled vehicles or street furniture), there are still possibilities for injury.
The bogus alarms are a real problem. Too many and people will ignore the alarm system, eventually the alarm will be real but will be ignored (just like the little boy who called wolf). The planned drills are good, that takes care of one third of the alarms. The drunk and the smoker were probably breaking existing campus rules and should be dealt with by the administration (most American campuses have all smoke free housing and rules against drinking on campus). The cookers were just accidents (unless there is a regulation against cooking in the residence halls) you have to put up with a few honest mistakes when you live in a building with other people, but if the accidents get too frequent maybe the people that are causing the accidents should have to pay for the response.
Bushings are a sleeve, usually made or a soft, semiporous material like bronze or brass. They are semiporous to hold lubricant. Bearings come in different varieties and are usually made of a hard material, like stainless steel or iron. A bearing has 3 main parts, the race (inner piece) the rollers (ball bearings/needles) and the carrier (outer piece) which contains the rollers. They usually are designed with space in them to hold a lubricant, such as grease. There are also flat bearings, made of a softer metal for use in engines for main and cam bearings. These are lubricated by the engine oil via the oil pump. The purpose of both is to reduce friction and wear and tear on rotating parts.
