The following three example problems demonstrate how to calculate torque. Example Problem 1 - Calculating Torque A 1.5-meter long bar is oriented horizontally and pinned so that it rotates about its left end. A 20-N upward force is applied to a point 0.4 meters from the left side of the ...
To calculate the net upward lift force on the plane, we can use the equation F = P x A, where F is the lift force, P is the pressure, and A is the wing area. We can also use the equation P = ρ x V^2, where ρ is the density of the air and V is the speed of the ...
Instead, when the crane's upward force precisely balances the weight of the load, a tension T (force per unit length) is preserved in the rope. The load moves upward when the motor drives T above this point, assuming the cable is strong enough to withstand the power. Also Read: Electric...
Here, k is the spring constant for the spring in question and m is the mass of the ball. The spring constant is measured in Newtons/meter. Springs with higher constants are stiffer and take more force to extend. To calculate the natural frequency using the equation above, f...
For several years, scientists have noticed a general upward trend in the general population's IQ scores. It has seemed that each generation is a little smarter than the one before it. Researchers aren't sure whether improvements in education, nutrition, medical care or society in general are ...
One way to approach this problem is to draw a cross-section of the cup, that is, what is looks like from the side after being cut exactly in half perpendicular to your field of view. If you draw vertical lines upward from the two points where the base meets the sides to the top of...
A skydiver exiting an aircraft will instantly experience the pull ofgravity-- the force of weight. If he or she is wearing a wingsuit, then the suit's airfoil will provide lift. However, the airfoil isn't large enough to accumulate enough lift to push the flyer's weight upward through ...
Notice that doubling the force by adding another dog doubles the acceleration. HowStuffWorks So, what can you do with Newton's second law? As it turns out, F = ma lets you quantify motion of every variety. Let's say, for example, you want to calculate the acceleration of the dog sl...
