14. How do you describe the direction of the weight and normal force? D A. The two have the same direction. B. The magnitude of these two forces is always equal. C. The two are always in the completely opposite direction. D. The two have different directions regardless of the surface...
I'm working on crashes against inclined barriers, and I need to compute the force normal to the barrier. I tried different options implemented in LS-PrePost, but none of them gave me the desired output. The only thing that seemed to work was to download
You're not asked for the separate friction force at this stage, so just calculate R, the total reaction force (normal + friction). That makes only two forces on the hamster … R and mg. So R = … ? Then use minus R for the block. May 18, 2008 #3 bcjochim07 ...
Newton's second lawis the one of greatest interest if you want to calculate force, or determine mass or acceleration if given information about the force and one of the other two quantities. Acceleration is a change in velocity. Examples of Forces You can think of a force as something that...
In summary, before finals, you decide to visit an amusement park in the Metrodome with your favorite niece. While waiting for her to ride the Ferris wheel, you calculate the total force on her when she is one quarter revolution past the highest point. This location is ...
It is also used to understand the relative economic burden of the workforce and has ramifications for taxation. The dependency ratio is also referred to as the total or youth dependency ratio.1 Key Takeaways The dependency ratio is a demographic measure of the ratio of the number of dependents...
How do you calculate the magnitude of acceleration in a velocity versus time graph? How does Newton's Second Law affect the motion of an object? In the centripetal force equation, what is the mass equal to? If I only know the average velocity of a moving object, how can I calcu...
You don't have to think about breathing because your body's autonomic nervous system controls it, as it does many other functions in your body. If you try to hold your breath, your body will override your action and force you to let out that breath and start breathing again. The respira...
What is the use of a force triangle? Define normal force Two forces pull on an object at the same time. Their resultant force is greatest when the angle between the forces is what? How do you calculate the net force of an object? Is tension related to the normal force? ...
Use the full bore piston diameter to calculate the full bore area (A) in meters squared (m2) by substituting the value you obtained from your diameter measurement into the equation A = π d2/4. π, or pi, is a constant value used in mathematics. It denotes the ratio of any circle'...
