1/12/2016 · You need to know the mass to figure out how much force you need to move it. For our first example, we'll use a person lifting a weight from the floor to her chest, and calculate how much work that person exerts on the weight. Let's say the weight has a mass of 10 kilograms (kg).... The required clamping force can be calculated from the cavity pressure inside the mold and the shot projected area, on which this pressure is acting. There are variables that affect the clamping force calculation, like the material type (low-flow versus high-flow plastic), and the depth of the part.

**How can you calculate the force to break something without**

4/09/2013 · The expected range of force needed to compress an oring 20% with a 0.070” diameter cross section (purple) that is 50 durometer is between 4.5 and 14 pounds per linear inch. The variation comes from differences in the compressive modulus of elasticity between different types of materials and different recipes.... Basically what I'm gathering is that without testing it, you simply CANNOT calculate the force to break it. I was going around saying that it's weight in pounds was its its pounds-force, and multiplying by 4.5 will give you the newtons to break it.

I need to create a table with the data of the dynamic time and with the data of the velocity, in order to integrate te tables with de INT function View Got a technical question? how to grow hibiscus from seed Our target is 9 bar so we need to see how hard you would need to push on the lever to get this kind of pressure on the piston. Remember that you have a mechanical advantage of 8.4. This means that your pushing force is multiplied 8.4 times. Note: If you choke-up on the handle (grabbing it closer to the machine) then you will decrease your mechanical advantage.

If F=MA with F being force, M being mass, and A being acceleration, does this mean that for a 50kg object, I need 50*9.8 (gravity) = 490 kgs of force?

## How To Find How Much Force Is Needed

30/12/2009 · Best Answer: You use the impulse-momentum theorem. If you divide momentum by velocity, you just get mass. So: FΔt = Δp F = Δp / Δt Note that this is average force. You get the car’s mass from part of your question, but also note that I converted kmh to m/s (SI units) and that the mass of the car makes

- Since we needed 6 inches of crushed stone, we used 0.5 feet for the height (that is, we converted inches into feet). If your number comes out as a fraction -- and it probably will -- round up. In the example above, you would round the 3.7 cubic yards of crushed stone to 4 cubic yards of crushed stone.
- Thrust is measured in “pounds of thrust” in the U.S. and in Newtons in the metric system. 4.45 Newtons of thrust equals 1 pound of thrust. A pound of thrust is how much thrust it would take to keep a one pound object unmoving against the force of gravity on earth.
