Impact Force Calculator - Calculate the impact force in a collision

First, we need to convert km/h to m/s, which gives us 27 / 3.6 = 7.5 m/s. Then we apply the first equation since we know the deformation distance, which is 75 cm = 0.75 meters. Replacing in the formula we get F avg = 0.5 · 2400 · 7.5 2 / 0.75 = 90 kN and a maximum impact force of 180 kN. ( calculation link) Example 2: Using the situation in ...

Also, material strength is tricky business. How much compression (push together) strength does rope have? None. But it has plenty of tensile (pull apart) strength. Concrete is the opposite -- it has great compression strength, but relatively poor tensile strength, which is why it needs reinforcement from rebar, high-tensile strength fibers, etc.

are birds mouth cuts really needed anymore? - JLC Online

04-26-2013, 09:43 PM. Re: are birds mouth cuts really needed anymore? If you don't cut the birds mouth, there is a point load at the outer edge of the beam or top plates instead of being spread across the surface. if the rafter is cut properly, it is well supported. A low slope of 1/2 in 12 would not get a birds mouth.

Wood Strength - Workshop Companion

A good indicator of a wood's strength is its density — the weight for a given volume. This is measured by its specific gravity — the weight of a volume of wood divided by the weight of the same volume of water. Generally, the higher the ratio, the denser and stronger the wood. This is not always the case, but specific gravity is a useful ...

How to Calculate the Weight of a Load Before an Overhead Lift

Here's how you would calculate the load weight of a block of aluminum that is 6 feet long, 3 feet wide, and 4 feet tall: Volume = Length x Width x Height. Volume = 6 feet x 3 feet x 4 feet. Volume = 72 cubic feet. Aluminum weighs 165 pounds per cubic foot (based on the numbers from the table above).

How Cement Is Made

The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. After quarrying the rock is crushed. This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches. The rock then goes to secondary crushers or hammer mills for reduction to about 3 inches or smaller.

Subgrades & Subbases for Concrete Slabs - Concrete Network

Concrete strength also comes into play, but most slab concrete is around 3000 to 4000 psi, so it's not a major factor. The tensile strength of concrete is typically taken as 10 to 15% of the compressive strength, so only about 400 or 500 psi. Compare that to the tensile strength of Grade 60 rebar, which is 60,000 psi.

Maximum Load of Cinder Block? - DoItYourself

The specifications (ASTM C90) for hollow load bearing concrete masonry units require that the block has a net compressive strength of 1900 psi. Since a 8" block is about 50% solid, it would take about 120,000 pounds to break it. The load you put on it in a building is much less because of a factor of safety. This is for a minimum strength block.
