Question:

Please help me solve this I have been working on this for 5 hours I'm lost?

Imagine a crane with 3 parts which have weights of W1 3500 lb W2900 lb and W31500 lb and center 3 centers of gravity respectivelyFrom the load it is carrying to the tire it is 10 ftto the tire to the first center of gravity G1 is 3ftfrom G1 to G2 is 8ft and from G2 to G3 is 6ftWhat is the reaction on each of the 4 tires if the load is hoisted at a constant velocity and has a weight of 800 lb? THEN with the boom held in the rest position or “on the ground” the maximum load the crane can lift without tipping is? You’re a statics genius if you understand this!Thanks

Answer:

LOL! Star Trek:) CoolYESI believe it will, or some transparent material stronger than glassIt'll happenMaybe in the next 50 years or soWe seem to be advancing pretty fastSo, who knows? We may have hover cars before I die:) Maybe a resort on the MoonAll we can do is wait and see.
Yes it will and may already be in useIt was revealed in popular mechanics magize that the front windshield of the President's limo USA One is actually transparent steel not plexiglass so yes it already exist since transparent steel does Good question
Aluminum is a metal, and metal cannot be transparent due to it's molecular structureTry some saran wrap for now! ;)
PerhapsCrystal glass has 30% of lead, so the fact of being a metal wouldn't be an issueSee the link below, other metals are used as wellSo maybe Aluminum is not out of questionAnd I find your question quite interesting, good luck on your research
You’re a statics genius if you understand this! Well, I can't argue with that, and I might add, a physic genius if you can understand it as statedand without an illustrationYou give (sort of) the location of a tire (singular) then ask about the reaction on each of the 4 tires, where are the other three? Tires aside, I'm still having a lot of trouble visualizing the problem.
