Load ratings for CEMA idlers, lbs Notes: 1. Troughing idler load ratings (Tables 5.7–5.10) are for three equal length rolls. 2. Load ratings also apply for impact rolls. 3. Troughing idler load ratings are based on a load distribution of 70% on center roll …
Vehicle load is a static distributed load in the middle of the longest tube and is 1/3 the tube length. Loading in the middle of the longest tube is a worst case for stress on a cage member. Square tube assumes bending with one side parallel to the load (think square vs diamond). The safety factors use the numbers in the table below for strength.

The mass of material Mm (live load) per meter (kg/m) loaded on a belt conveyor is given as: V c Mm 3.6...(3) where c = Conveyor capacity (4 tones/hr); and V = belt speed (1.25 m/s). Mm =0.889 kg. The magnitude of belt speed V (m/s) can be determined from equations 1, 2, 3 or 6 and can as well be gotten from the catalogue for standard belt.
In order to find the maximum tension is necessary to calculate the effective tension, that is, the force required to move the conveyor and the load at a constant speed. The calculation of the total tension is based on a constant speed of the belt including the necessary basic conditions to overcome the frictional resistance and tension forces.

The higher the speed (at a given load), the more power we need. The calculations behind this look as follows: P (kW) = F (N) x V (metres/min) / 1020 x 60 In which P = power in kW, F = Force (line pull) in Newton, V = Line speed in metres/min, 1020 is a constant and 60 is a translation from minutes into seconds (Nm/sec).

Let's say that we want to determine the HVAC load for a residential building that has 1000 square feet, 8 ft tall ceiling, 5 windows, and 2 exterior doors, that is occupied by 3 people. The HVAC load calculations would look like this: 1000 sqft (house surface) x 8 ft (hight of the ceiling) = 8000. 3 (occupants) x 100 = 300.

Determining Load Limits. First, determine the size, the spacing and span, and the species and lumber grade of your floor joists. Look for a stamp on the joist that indicates the lumber's species and grade. Use a design value table to find the Fb value for your floor joists. As an example, consider a room with a floor area of 10 feet by 11 feet ...
Cooling Load Calculation Example. To calculate the estimated HVAC load for a house with 2,500 square feet, 12 windows, and 3 exterior doors occupied by 4 people, simply plug it into this formula: 2,500 x 25 = 62,500 base BTU. 4 people x 400 = 1,600. 12 windows x 1,000 = 12,000. 3 exterior doors x 1,000 = 3,000.
6The 0.6 reduction factor on D is intended to apply to the calculation of net overturning stresses and forces. For wind, the analysis of For wind, the analysis of overturning should also consider roof uplift forces unless a separate load path is designed to transfer those forces.
main load-carrying tension yarns. Fill yarns are then laid transversely and alternately, above and below the main tension yarns. This construction gives greater dimensional stability to the belt, and does employ a "beam" effect for better load support and transverse rigidity. The yarns used are much thicker than yarns in conventional fabrics.
For example, if building is 24′ x 24′ and has trusses, and the load on the roof will be for 30 lb snow load and a ceiling with no storage will total out like this. This will amount to twice as much load on the exterior walls compared to a building with a center wall. This calculator takes all of this into consideration.
The term Take-Up refers to a variety of devices that are used to provide adjustment in the amount of belt tension on a conveyor system. Since many of these devices require manual calibration, adjustment of belt tension with a take-up mechanism requires training and an understanding of how belt tension affects conveyor load. If not
Load Calculation on Column: Volume of Concrete = 0.23 x 0.60 x 3 =0.414m³; Weight of Concrete = 0.414 x 2400 = 993.6 kg; Weight of Steel (1%) in Concrete = 0.414x 0.01 x 8000 = 33 kg; Total Weight of Column = 994 + 33 = 1026 kg = 10KN; Wall Load Calculation.
