Q: If I have a 10 foot board that weighs 100 pounds and lifted one end with a weight scale and left the other end on the ground, what would the scale meausurement read in pounds at the first point of lift and how might it change as it is liftedLink suggestions to answer are welcomeThank's: easy stuff think of the board as if it were a peice of string 10 Ft long with 50 Lbs at each endthe scale would read 50 Lbs when first liftedbut because its a board the same applies iethere is 50 Lbs supported by the ground 50 Lbs on the spring balanceas you lift the board more weight is transfered to the end on the ground ie at 45 degrees then half the weight from the spring balance end is transfered to the end on the groundmaking that end weigh 75Lbs so the spring balance is only holding 25 Lbsthe weight on the spring balance continues to fall untill the board is verticalthen the spring balance holds no weightany further lifting will put 100% on the balance making the reading 100LBS Weight Vs Angle The angle at which a sling holds a given load influences the effective weight of the loadStresses are minimal for loads with slings held perpendicular to the load, as shown in Figure AFor distributing the load vertically among more than a single leg of a sling, a spreader bar may be usedAs shown in figures B-D, increasing the angle of the sling to the hook from 30 to 60 degrees increases the effective mass of the load from 1154 lbs to 2000 lbs, essentially doubling the weight on each leg of the sling at 60 degreesThe chart in the middle offers a handy guide for assessing the effective angle of the sling to the relative weightThus, it is always better to limit the angle of the slingFurther, such changes in sling angle must be accounted for in lifts that are close to the sling weight limit and/or for critical lifts (greater than 90% of the crane limit)Crane operators should download a copy of this chart and carry it with them during crane operations.

Q: I was only 4 years old and I was at school and I remember there was a helicopter that landed on the field of my elementary school and the kids and I looked out of the window and my pre-kindergarten teacher was closing the blinds and the school went on lockdown and parents had to come and get us from school because they were very scared because nobody else knew where it was going to happen againWhat's your story?: I had a front row seats to the whole thingI was a Construction Project Manager for New York City's Water and Sewer Utility, in charge of a pier replacement project at one of our sewage treatment plants in BrooklynI was standing on the deck of a construction barge from where I had a great view of the East River and Manhattan from the 14th Street all the way to South FerryThe contractor had just finished driving a pileThe crane lifted the pile hammer off a pile and was turning to lay it down on the bargeAs I watched the hammer, I noticed an airplane flying unusually lowAs I stood wandering what was going on, the plane crashed into the North Tower Later I was in our field office when another engineer working with me run in and told me that a plane had crashed into the World Trade CenterIt took a few seconds for me to realize that he was talking about the second planeI didn't see the South tower collapse, but I did see the North Tower collapse.

Q: What is PCI?What is PCI Express?What is a network hub?What is network switch?What is Network Bridge?What is network router?How many virtual machines can we run on a single physical host?: convert amps to volts.and i think volts should tell you something about how fast the reaction is happening (volts force of electron movement)

Q: a)The tower crane has a sliding pulley block which is 20 m from the mastThe counterweight has a weight of 250000N and it is 5m from the mastWhat is the maximum the crane can lift?b) what is the mass of this load?c) the load moves 10m along the jib towards the mastWill the maximum weight that can be lifted increase or decrease?d) if the counterweight moves to 6m from the mast what is the maximum weight that can be lifted if the load is 20m from the mast?e) for health and safety reasons the load lifted should be less than the maximumWhy do you think this is?TA ! x: a) is easyIt will be (250,000/4), 62,500Nb) (62,500/9.8) 6,377.55kgc) It will increase (double)d) (250,000 x 6) / 20 75,000N., or if you need mass, divide that by 9.8e) The crane could collapse if the maximum or near maximum load is liftedIt is safer to have a reasonable margin for safetyThe danger to health should be obviousTower cranes are very tall.
