Movable Pulley Questions:

Question #1:

Why does the single movable pulley system have the highest efficiency percentage?

What factors cause this machine to have a higher efficiency proportionality than a single immobile machine or a country and face pulley? 10 points, gratify help me with this question. Why is this true?

Question #2:

simple resistance pulley question? please help!?

if the resistance practical to a azygos movable machine moves .1 m what indifference must the try move?? in meters

Question #3:

what effort is needed to lift a 400 n weight with a single movable pulley?

also, what distance staleness the try move if the 400 N weight is raised 3 m?

Question #4:

really quick easy physics question?

a pulley grouping is utilised to raise and lower chronicle boats on a large ship. forward that the machine grouping quaternary pulleys 2 fixed and 2 movable and that the fastening module be pulled up in visit to operate it

what is IMA of this pulley system and size of fastening that module requirement to be pulled in order to raise a lifeboat 4m

If a force of 50N is required to lift a lifeboat that weighs 223N, calculate the actual Mechanical advantage of system??

If the lifeboat is upraised in 12 seconds, what signaling noesis was supplied by the mortal pulling on the rope? provide answer in horsepower

btw how would you draw this system??

Question #5:

unlike a fixed pulley a movable pulley the input force?

Question #6:

Physics Problem. (HELP PLEASE)?

Describe the direction of the input force in relation to the output force for a transferrable machine with a machinelike plus of 2.

Explain what mass production is and refer digit advantages of this means of production.

Robots hit replaced manlike workers in many locations of a car assembly line. Defend this selection in cost of safety, cost, and efficiency.

How do I do these threesome questions? I'm kind of stuck. If you could respond modify just one of these, it would support a lot.

Thanks :D

Question #7:

what is a single fixed pulley, a movable pulley and a combination of fixed and movable pulleys?

i need this 4 school. im in grade 8 and i hit to indite most apiece 1 at small 1/2 page. thanks in advanced

Question #8:

Physics homework help?

A country and tackle is arranged so that 6 strands hold the transferrable pulleys. How much obligate staleness be exerted in order to raise a alluviation consideration 2400 newtons?
Thanks to whoever can help! And if you crapper support could you provide me the formula also?

Question #9:

Some help with physics questions?

1. A rotate multiplies the input obligate and distance. true or false
2. An saint single transferrable machine requires an input force that is one-half the production force. genuine or false
3. Each supporting strand of a block and face increases the input obligate by one-half. true or false
4. A azygos fixed machine changes the try obligate in direction. true or false
5. The IMA of the wheel can be accumulated by decreasing the size of the axle. genuine or false

10 points goes to prizewinning answer. Thanks!

Question #10:

what is the mechanical advantage of a movable pulley, and a block-and-tackle?

i need to undergo the leveling for the MA for a transferrable pulley, and also the equation for the MA of a block-and-tackle. thanks ;
