- Q: If you could give me an equation that would be great, trying effectively to calculate the size of a counterbalance needed to keep a weight on the end of a lever level. thanks!
- force * distance = constant. I can't quite see the arrangement you're describing, but the force*distance you need will be the same as 200*15 = 3000, if the 200lb is at the free end of the lever. If it's at the pivot end then the distance will be a lot smaller and the force at a distance of 15ft will be less. Edit the only basic is moments = force x distance. Shoulders are complicated. Imagine a see saw in a playground. For the see saw to be level the force x distance on each side must be the same. If you are with a small child and the child is at the end of the see saw then you need to sit closer to the center for the moments to balance.
- Q: We have friend who's an excavator that said he'll help us make a french drain. Now, how to clean up the musty probably moldy but definitely dirty basement? It's unfinished, and really wet right now. My husband wants to spray the whole place with bleach and close the door for a week. Bad idea?
- That is a good fix, and it will work. Use pool chlorine instead as it has more bacteria killer than store bleach, and its usually the same price. Drywall holds moisture, so if you have raw drywall figure a way to get it behind the face of the drywall, this will work for about 2 months. No drywall and the pool chlorine will work well.
- Q: :/I really wanna work at a place where i like.I really love anime/manga/video games.I wanna work somehwrere close by.Because i get homesick quite easier than other people.
- Most places I know of, you need to be 14 to legally work. So, a job caring for the grounds would be something entirely appropriate for a young person. Mowing lawns, and so on.
- Q: Its likea a claw thing,,, similar to a crane but looks like a claw big machines used in construciton~
- Rock-ripping heavy duty Excavators have buckets with big teeth.
- Q: I would like to know where to find any information on how to start and run a construction equipment rental business. I would like to rent things such as backhoes, bulldozers, excavators etc. I am curious about many things such as financing and the overall all scope of the business and how to start and run it succesfully.
- Go to the link below and in the search, type in 'equipment rental'. They have model plans that you can use for your business. They will either be free or of reasonable cost.
- Q: my excavator hose has a leak. i installed new hose. the hydraulic oil was partially drained without my knowing. I started it but no response. I add oil but has no power. what would I do?
- It entirely depends on where in the system the replaced hose was. If it was on the suction side of the pump, there may be trapped air that needs to be purged before the pump will start to pump again. If on the pressure side, it would not cause what you describe. Another thing is if the controls are pilot valve operated and the pilot system got air in it, it would need to be bled out. You may need to contact the service department at a dealership and ask for some help.
- Q: today, a guy left his backhoe running for 5 straight hours without even useing it............
- ribuckeye is correct. A diesel engine operates off of the principal of heat. They do not run well, or operate efficiently until they are warmed up. If you were ever to go to a railroad yard, you would find that the locomotive's diesel engine is rarely ever shut off. However with the high cost of diesel fuel, many trucking companies now require their drivers to shut off the engine when it is not in use, as a cost savings measure.
- Q: What kind of industry does excavator belong to? What's your occupation?
- Excavators belong to the construction machinery industry, excavators usually require excavators, driving license, of course, there is a master band, there is no evidence, the problem is not large.
- Q: Me and my husband are starting a equipment rental business (like bobcats, excavators, trenchers). We are trying to come up with a business name that sounds professional. Our last name is neal and we were thinking about incorporating that but would also like some other ideas. please help!!! thanks
- Please edit your posting. Include your last name, the area you are in (State, County, Town, and any nickname of the above). Is your area historic for any reason? Is there a river nearby or other point of interest? Let us have more to go on. For example, in Lyons County there is the High Desert tourist area. If you were there, I could recommend LHD: Long, Hard, and Deep. Actually, for more professionalism, I would take Lyons High Desert and come up with other things that have the initials of LHD. But you have the idea now.
