says that there is an attractive for pulling on objects with mass. the magnitude of this force is proportional to the product of the masses of the two objects interacting and inversely proportional to the square of the distance between the objects. i can write the magnitude of this force as...
P res" = Pa" With steady-state motion of the circulating liquid, the force Pres is made up of the forces due to tangential stresses, and forces arising due to the restructuring of the velocity profile with a change in the direction of the motion of the flow.* Taking account of the con...
An elevator with a tension force of 4000 N in the cable is accelerating upwards. The total weight of the elevator is 3400 N. If the mass of the elevator is 347 kg, determine the acceleration of the elevator. (Use g=9.8 m/s2). 3. Two elephants are trying to pull a wo...
12 m at a constant speed with a rope that weighs 0.8 kg/m. Initially the bucket contains 36 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 12 m level. How much work is done? Work = Force*Distance Force = Mass*Accelerati...
Practice Calculating the Normal Force on a Level Surface with practice problems and explanations. Get instant feedback, extra help and step-by-step explanations. Boost your Physics grade with Calculating the Normal Force on a Level Surface practice probl
The normal force is the force that a surface exerts on an object that is in contact with it. It is always perpendicular to the surface and is equal in magnitude to the force that the object applies on the surface. The normal force can be calculated by multiplying the mass of the object...
Read about calculating the small-signal electrical and mechanical parameters of a speaker driver model in this Learning Center article.
Acceleration:Acceleration is the rate of change of velocity with respect to time. Acceleration refers to how quickly the velocity of an object is changing. Newton's Second Law of Motion:Newton's second law of motion relates net force on an object to the objects mass and acceleration...
In summary, a 60 m long bridge with a mass of 51800 kg is supported at each end. A truck weighing 45000 kg is placed 26 m from the left end. The problem is to determine the force on the bridge at the left point of support. To solve this, you need to use the sum of forces ...
