What is the force of 3 pounds falling 5 feet?
a bruise.
How many pounds of force must a man exert on one end of a 10 ft lever to lift a 200 lb rock on the other end if the fulcrum is 2 ft from the rock?
to balance moment 10 feet x force = 2 feet x 200 force = 40 pounds
How much force is generated when a 260lb man falls 6 feet?
Something about 1550 foot pounds, or 2115 joules.
What is the mathematical formula for calculating work?
The mathematical formula for calculating work is: Work = Force × Distance × cos(θ) where: Work is the amount of energy transferred or expended; Force is the amount of applied force; Distance is the displacement of the object in the direction of the force; θ is the angle between the direction of the force and the direction of displacement.
A falling stone travel the same speed each second it falls?
A falling stone will increase in speed until it reaches it's terminal velocity, the speed when the downward force of gravity equals the upward force of drag, which causes the net force on the stone to equal zero, thus achieving an acceleration of zero. If atmosphere is ignored, a falling body will accelerate at 32ft/s (9.75m/s). The distance traveled in the first second would be 16 feet (4.87m), in the second second: 48 feet (14.63m) and in the third second: 80 feet (24.38m); hence after three seconds an object would have fallen 144 feet (43.89 meters) and is traveling at 96ft/s (29.26m/s).

Levers explain how the force applied by a lever is affected by its distance from the fulcrum?
On the side on which the force is being applied, the distance and force are directly proportional. On the other side of the lever, they are inversely proportional. If 1 pound of force is applied to a lever at 1 foot on the left side of the fulcrum, the lever will apply 1 pound of force 1 foot from the right side of the fulcrum. If 1 pound of force is applied 2 feet left of the fulcrum, the lever will apply 2 pounds of force 1 foot from the right side. If 1 pound is applied 4 feet left of the fulcrum, the lever will apply 4 pounds of force 1 foot to the right of the fulcrum. If 1 pound of force is applied 1 foot left of the fulcrum, at 2 feet on the right side, the force will be 1/2 pound. At four feet, it will be 1/4 pound. Etc,
A 150 pound man is standing on a lever one foot from the fulcrum. How much effort must be used to lift the man if the effort is applied six feet from the fulcrum?
6 x 150 pounds. 900 pounds of force would have to be applied.
What is the difference between ft pounds and pounds ft?
There is no difference. It is (force x distance) or (distance x force). It is usual to express torque and moment of a force in pounds-feet and work done in foot-pounds but it is not mandatory.
Nm to ftlb conversion?
Newton meters (Nm) multiplied by 0.738 = Pounds-force feet (lbf ft; lb ft). Pounds-force feet multiplied by 1.356 = Newton meters.
When measuring torque is a two foot-pound measurement the equivalent of two pounds of force applied one foot from the pivot point or one pound of force two feet from the pivot point?
The way torque works, these two cases give the same torque, or twisting force, to the object at the pivot point. To find the torque applied, multiply the force by the distance. Obviously this is the same in the two cases you describe.
How does a pulley change the input force?
A single pulley only changes the direction of the applied force. A second or more pulleys on the same rope will multiply the force applied by decreasing the distance of the applied force. This arrangement is called a block and tackle. Two pulleys double the force and halve the distance the force acts upon the mass. Three will triple the force while reducing the distance by 1/3, and so on. If 1 pound of force is applied to a rope with four pulleys on it over the distance of 10 feet of rope it will raise a 4 pound weight 2 1/2 feet.

What is the difference between 47 ft- lbs and 47 in-lbs when torquing fasteners?
0
How much work is performed when 500 lb of force is applied over a distance of 6 feet?
a 500lb force moving through 6 feet does 3,000 foot-lbs of work.
How fast is a car going that it takes 131 feet for it to stop?
It depends on the decelerating force applied by the brakes.
Is 150 pound-feet of torque much different from 100 pound-feet?
for a given lever length the force is (150 / 100) times greater torque = force (pounds) * lever length (feet)
