which largely determines its resistance to changes in motion -- or inertia. For things that rotate or spin, however, the picture becomes more complicated; instead of mass, physicists talk about an object’s moment of inertia. An object’s shape strongly affects the moment of inertia, as does...
The Basics: What Is a Vector? The first step to understanding what it means to calculate the magnitude of a force in physics is to learn what a vector is. A “scalar” is a simple quantity that just has a value, such as temperature or speed. When you read a temperature of 50 degree...
In summary, torque is a measure of how well an object resists rotational motion and is calculated by multiplying the force applied by the distance from the axis of rotation. The moment of inertia is the sum of the products of the mass and squared distance of each object piece from the ...
How to Calculate the Moment of Inertia of a Beam Section Before finding the moment of inertia (or moment of area) of a beam section, its centroid (or center of mass) must be known. For instance, if the moment of inertia of the section about its horizontal (XX) axis was required then...
How can I manage to express θ with dv so that I no longer have to handle it? I know v=Rextdθdt v=v0+dv But I'm stuck here because I don't know how to calculate dθ in function of dv as dv depends of dθ too It appears like you didn't let the angel change in your...
\text{average impact force}=\frac{mgh}{d} Completing the Calculation The hardest part to work out when you calculate falling object forces is the distance traveled. You can estimate this to come up with an answer, but there are some situations where you can put together a firmer figure. ...
I am trying to calculate the friction force due to a sliding o-ring. In this case, the o-ring has compression from the slider and also has contact with the side-wall of the groove. I can only find the calculation when there is no contact with sidewall. Please give me your 2 cents....
How to calculate g-force?A 35,000 kg plane travelling 120 m/s turns in a full circle, the period being 12 s. If the plane maintains constant altitude and velocity, what is the g-force on the pilot?Follow • 2 Add comment More Report ...
So IMHO this is not a good system to solve or design. Perhaps you need to apply a horizontal force to the rolled end of pivot linkage at all time to keep it structurally stable. In this case why do you use cable connection than? RE: How to calculate restoring forces/reactions for st...
When we know the tensile strength and shear strength of materials, it is easy to calculate their blanking force. Let’s take a look at this picture: The above picture is the calculation method of blanking force. However, in the actual value, need to consider the safety factor K separately...
