Question 1: A spring has a forced constant of 3 pounds per inch. How much force is required to move the spring 12 inches?( The force required to stretch a spring is equal to its force constant(k) multiplied by the distance stretched(x) F=kx

Answer:

36 pounds Question 2: When leo is driving his car, He exerts 50 newtons of force on the steering wheel to turn the corner into his driveway. The shaft exerts 300 newtons of force to turn the wheel. What is the mechanical advantage of the system.

Answer:

6

Question 3: Mechanical advantage is equal to what

Answer:

Output force divided by Input force

Question 4: The formula for force on a spring

Answer:

F=-kx

Question 5: The shock absorber on a car is a very large spring if abras car hits a pothole with 600 pounds of force, and the shock absorber compresses 3 inches, what is its spring constant in pounds per inch.

Answer:

200

Question 6: F1×D1+F2×D2=F3D3

Answer:

(25×10)+(30×5)=F3(10)

40 pounds

Question 7: equation for lever

Answer:

weight1×distance1=weight2×distance2 Question 8: If you did 70 jewels of work pushing a table 3.5 meters across the room, How much force did you apply.(w=Fd)

Answer:

20 newtons Question 9: While throwing a football, Dan exerts a forward force of 50 newtons on the ball and pushes it forward a distance of 1.2 meters. How much work does he do on the football?

Answer:

60 joules work=force×distance Question 10: Term refers to the push or pull on an object that can cause it to accelerate

Answer:

Force Question 11: Mr.nelson is filling his grocery cart with food. If he uses a force of 26 N to move his car 15.2 m. How much work does he do.(work=force times distance)

Answer:

395.2

Question 12: How do input force and output force relate to each other

Answer:

Output force can be smaller or larger than input force.Input force can be equal to output force, but output force requires input force to exist Question 13: Jose is lifting a 405 pound block using a lever. If the block is 3 feet from the fulcrum and jose is 9 feet from the fulcrum, How much force must be applied to lift the block.((F1)×D(1)=(F2)×(D2))

Answer:

495×3=(F2)×9 solve for 135 Question 14: 55,009 joules if work are done to move box 25 meters.How much force is applied?(W=Fd)

Answer:

2,200 newtons Question 15: If a force of 210 pounds is exerted over an area of 15 square inches,what is the psi?(P=F÷A)

Answer:

14 psi Question 16: Dolores wheels her wheelchair upgrade by using a force of 80 newtons. If the ramp has a mechanical advantage of seven what is the output force.(outputforce=MA×inputforce)

Answer:

560 Question 17: A force of 70 newtons is applied to a nutcracker to Crack open a pecan. If the mechanical advantage of the nutcracker is 3.5, What force does the nutcracker apply to the pecan.(ma=output÷input)or 3.5=x÷70

Answer:

245 newtons Question 18: Maddox does 25,000 jewels work pushing The box of his toys 20 meters to his room.(W=Fd)
