Tube Calculator - Rogue Fabrication

Apr 06, 2017· 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.

How to Calculate Floor Load Capacity | Hunker

The dead load on a floor is determined by the materials used in the floor's construction. A typical wood-frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot; if there's wall-board covered ceiling suspended from the underside of that floor, the dead load increases to about 10 pounds per square foot.

The values in Tables 1 and 2 are generated assuming dry conditions, normal duration of load and untreated, Exposure 1, structural pan-els. For other conditions, the loads should be appropriately adjusted using the factors given. See the examples for proper

Beam Loads - Support Force Calculator

Example - A beam with two symmetrical loads. A 10 m long beam with two supports is loaded with two equal and symmetrical loads F 1 and F 2, each 500 kg. The support forces F 3 and F 4 can be calculated (500 kg) (9.81 m/s 2) + (500 kg) (9.81 m/s 2) = R 1 + R 2 => R 1 + R 2 = 9810 N = 9.8 kN. Note! Load due to the weight of a mass - m - is mg ...

10 Most Common Reloading Mistakes - Shooting Times

Dec 03, 2014· When loading with a single-stage press, charge a complete case trays' worth of cartridge cases. Before seating bullets in them, use a flashlight to scan the tray for any cases with powder levels that appear high or low. If you're loading with a progressive press, spend the money for a powder level check system and install it.

Compressive strength - Wikipedia

Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to Tensile strength which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart). In the study of strength of materials, tensile strength ...


live loads (ll) can be calculated by using the boussinesq formula for a point load at the surface of the semi-infinite elastic soil or by using the predetermined values in the following table: live loads on pvc or hdpe conduit or duct (live loads transferred to conduit lbs/in2) height of cover highway railway airport height of cover highway ...


Crush Sleeve Design: If you are unsure about getting the correct pinion depth, it may be easier to install the pinion without a crush sleeve until the correct pinion depth has been established. Always use a new crush sleeve for final assembly. Slide the crush sleeve on the pinion shaft (unless you are using

Brush Crusher™ | Westendorf

Brush Crusher™ BC-3000 The new patented BC-3000 brush handling attachment makes those painful labor intensive tasks like clearing trees, handling brush, or even cleaning up after a storm--Fun!


W' = Live Load (lbs/in2): pressure transmitted to the pipe from traffic on the ground surface. Live Load values are found in Table 2. P = Prism Load (lbs/in2): pressure acting on the pipe from the weight of the soil column above the pipe (also called "Dead Load"). Prism Load values are found in Table 3.

Loads on Buried Pipes - CivilWeb Spreadsheets

This equation is presented below where P is the point surcharge load, H is the depth to the pipe crown and r is the horizontal distance from the load to the pipe centre. The CivilWeb Buried Pipe Design spreadsheet includes a calculation tool for estimating the vertical pressure acting on a pipe from up to 16 concentrated point loads on the surface.

Tranferral of Point Loads - JLC-Online Forums

Jan 14, 2010· Assuming point loads are distributed over the necessary number of studs is certainly wrong but engineering-wise an unsafe number. If a beam (not a joist) is transferring a load to a point on a wall, One might expect that the top plates would not support the load, but that some type of header could safely transfer the load to the entire wall.

Caught or Crush Injuries - Safe at Work California

E ach year, workers suffer approximately 125,000 caught or crush injuries that occur when body parts get caught between two objects or entangled with machinery. These hazards are also referred to as "pinch points." The physical forces applied to a body part caught in a pinch point can vary and cause injuries ranging from bruises, cuts, and scalping to mangled and amputated body parts, and ...

What is Compression Testing? The Theory and Applications

Nov 22, 2010· Vented: for crush/top-load testing of containers, such as PET bottles. Circular vents allow air to escape from the container during compression, and an integrated nose cone helps to position containers centrally, minimising bottle slippage. Fixtures are also available for applications involving flexure/bend tests and spring tests.

Wood Beam Design and Installation Considerations ...

Beam connections are based on how the load is applied (be it top, side or a point load) and the magnitude of the load. Side loads and point loads on beams typically require the most aggressive connection patterns in order to transfer the load to all plies of the beam TJ-9000 provides connection tables for side, top and point loads on beams.


1. Earth load is based upon the prism load concept, a conservative assumption for loads experienced by a flexible pipe in a trench. 2. Truck loads are based upon a single AASHTO H-20 truck with 16,000 pounds wheel load and an impact factor of 1.5 at all depths. 3. External load design includes calculation of both ring bending stress and deflection.

2 x 4 Strength? | DIY Home Improvement Forum

Aug 14, 2010· A distributed load creates a lower maximum bending stress in the beam than a point load of equal total weight at the center. Example: A 10 foot long 2x4 carrying a uniform load of 40 pounds per foot (400 lbs total load) will have a maximum bending moment at …

Understanding Corrugated Material Strength Ratings: Burst ...

Edge Crush Testing measures the force applied in pounds per linear inch of load-bearing edge and is reported as an ECT rating. 32 ECT is the most commonly used corrugated material. ECT has grown in popularity since its invention in the 1990s because it provides a better measure of how well boxes will hold up to stacking and palletizing.
