I am looking for information on designing the flights for a shaftless screw conveyor based on the pitch, diameter, angle of incline, etc.
I have the screw torque, motor rating, product density.
Maybe there is a design guide or sample calc somewhere.
thanks.
In the design of the drilled shaft to acommodate a long span rigid frame, how is the lateral force handled from the rigid frame reactions, which is substantial? Do you tie back into the slab or tie the columns together with enough tension reinforcing that the load cancels out?
I need an approach to come up with the longitudinal load induced by acceleration/deceleration of a car body mover in an automobile plant. The capacity of the mover is 3000 lbs and runs about 450 ft/min. I would the time to reach this velocity is about 1 sec.
I was curious how many engineers carry "errors and omissions" insurance when doing consulting work on the side, not as their main source of income, i.e. "moonlighting"
I have searched for the OSHA requirement for the minimum overhead clearance for maintenance platforms. Anyone have an idea? I have always used 7', but I think OSHA allows 6'-10" or 6'-8".
I have a few questions for the design of HSS.
1. Why are the property tables different for HSS in the LRFD design specification from the properties given in the AISC ASD 9th ed for TS sections?
2. In design, to allow for the torsional effects of eccentric loading, the LRFD spec combines the...
I am looking at a design of a water storage tank. The tank is not under pressure, so my design approach will be to accommodate only the hydrostatic pressure. This tank is rectangular due to installation constraints. The dimensions are 10'X4'-6"x18'tall. I am having a hangup on the...
I was looking for reference material for the design of a commercial swimming pool. I have very little experience in this, mostly trying to relate it to cooling tower basin design. This installation, I believe will be in an area with expansive clays. My contact mentioned putting the pool on...
I am doing an analysis of a carport that is already constructed. The allowable loading needs to be determined for permit purposes. I can't find any reference to live load for carport roofs in UBC. The closest I can find is the 12 psf for standard roof loading. The trouble is that the carport...
I would like to find a resource for the effects of temperature on the tensile strength of carbon steel and stainless. Say at 300 degree F, 500 degree F, 1000 degree F, 1500 degree F, etc
In the design of transportable skids constructed of structural steel, what kind of impact loading or safety factors should be applied to the dead load of the equipment for the structural steel design. All the equipment, piping, floor plate, insulation panels will be mounted to a steel skeleton...
I am looking for information (proprietary) on seismic snubbers. These will be installed on some fairly large (50hp) blowers mounted on vibration isolators. I have a good idea on what is required, just want to know of any manufacturers available. I'm thinking that bushings with neoprene...
I am trying to calculate the allowable stress for double angle beams used to support utility piping. The "stem" of the double angle is turned up, i.e. the stem is in flexural compression. I have some literature on wt shapes in this configuration, seems like a lot of derivations just...
