Q: Does shear deformation or cutting speed tool temperature more?Thanks for help.: Sheer deformation of the tool is negligible, therefore the deformation work converted into heat is very low. Excessive cutting speed will easily and quickly overheat the tool tip and may ruin its geometry and/or structure, depending on the tool material (hard metal or ceramic).

Q: Requirements for construction engineering personnel: 1. organization and coordination of mechanical equipment, asset management and status management methods and mechanical equipment management, job related personnel and equipment allocation, scheduling and scrap capacity

Q: in the indian mutiny what machinery was used in the war to fight?: Canon, musket and the sabre..typical machinery for the 1850's.

Q: if the company introduces new machinery and reduces its direct labour, how is the break even point affected?: It will be affected relative to the cost difference between the machine and labor . If the cost of the machine is more than labour in the short term it will be higher if not then lower . You should be able to calculate a realistic break even point for when the machine is paid off , obviously you need to take into account running costs and maintenance and whether or not they will exceed your existing labour costs . Cheers

Q: how to depreciate machinery by using weighted average?: It really depends on how you want it weighted. If you have the original value of your capital asset, your variable depreciation ratio based on the data for the weighted average, and the time period, it's really just a matter of calculation. Can you be more specific with your question?

Q: Anyone know anything about Machinery Technician (MK) in the coast guard reserves? Is it true they would train you on working with engines? Anyone know if positions are guaranteed in CG or no? The website says 12 weeks in Yorktown, VA, *or* on the job training, has anyone ever gotten on the job training for this position instead and where at?: the MK does all the engine repairs for the most part, aside from the muliti missions of search and rescue, law enforcement and boarding. the have guaranteed school IF there is availability. when you go to a recruiter as if there is or not for that time. on the job training is called striking. if you score high enough on your ASVAB you can have the option to strike, which means you will follow around a MK to learn everything rather than go to school. it takes a but longer but Worth it for people who really dont do well with classes. striking can occur where ever they send you-doesn't have to be one specific place
