What are the 5 machines?
The inclined plane.
How long does it take 100 machines to make 100 widgets?
5 minutes
If we have 100 machines working together, then each can make a widget in 5 minutes. So there will be 100 widgets in 5 minutes.
How long would it take to for 100 elves to make 100 dolls?
Essentially it takes 1 Elf 5 minutes to make a doll. Each elf takes 5 minutes to make one doll. It will therefore take 5 minutes for 100 elves to make 100 dolls.
Is the bicycle the most efficient machine?
It takes less energy to bicycle one mile than it takes to walk a mile. In fact, a bicycle can be up to 5 times more efficient than walking. A comparison of the energy cost of various forms of transportation shows that the bicycle is most energy-efficient.
How do machines work?
Machines simply transmit mechanical work from one part of a device to another part. A machine produces force and controls the direction and the motion of force, but it cannot create energy. A machine’s ability to do work is measured by two factors. These are (1) mechanical advantage and (2) efficiency.
How many simple machine are there?
six
There are six types of simple machines: the inclined plane, the wedge, the screw, the lever, the pulley, and the wheel and axle.
What is a widget and what does it do?
Android widgets are mini-apps that run on your Android Home screens. Widgets are not the same thing as the shortcut icons that allow you to launch an app. Android widgets generally display data and take up more space than a single icon. For example, weather widgets show data about local weather forecasts.
How fast do bicycles go?
The average speed for professional cyclists while traversing on flat terrain is 25-28 mph. The average amateur cyclist travels about 17-18 mph while on flat ground.
How fast does a bike go per hour?
The majority of riders can average a speed of about 15 mph on a one hour ride. A good speed for a beginner is 10 mph, but you should be able to get to 15 mph pretty quickly. If you start training every once in a while, you could get your average up to 18 mph, but training on a regular basis could get you to 22 mph.
How do simple machines work?
A simple machine uses a single applied force to do work against a single load force. Ignoring friction losses, the work done on the load is equal to the work done by the applied force. The machine can increase the amount of the output force, at the cost of a proportional decrease in the distance moved by the load.
What makes a machine a machine?
A machine is any physical system with ordered structural and functional properties. It may represent human-made or naturally occurring device molecular machine that uses power to apply forces and control movement to perform an action.
What is a wheel machine?
The wheel and axle is a type of simple machine used to make tasks easier in terms of manipulating force by applying the concept of mechanical advantage. The wheel and axle consists of a round disk, known as a wheel, with a rod through the centre of it, known as the axle. The wheel and axle both rotate at the same rate.
How many machines would it take to make 100 bicycles?
A) If each one of 5 machines working separately takes 5 minutes to make 1 bicycle; then 5 machines will take a 5 minute time span to make 5 bicycles. Cumulatively they would have used 25 minutes. Then 100 machines will take a 5 minute time span to make 100 bicycles.
How long does it take a machine to make an object?
Answer Wiki. All of the answers that “need improvement” are correct. If it takes 5 machines 5 minutes to make 5 objects, then each machine needs 5 minutes to make an object. If 50 machines are at work, then after 5 minutes, each machine will have made an object, and you will have 50 objects. The answer is 5 minutes.
How many widgets can 100 machines make in 5 minutes?
We’ve put together a list of 8 money apps to get you on the path towards a bright financial future. 1 machine make 1 widgets in = 25 ÷ 5 minutes = 5 minutes. now, 100 machine make 100 widgets in = 500 ÷ 100 minutes = 5 minutes. This is the easiest way to solve such type of questions….
How many people would it take to make 5 units?
If 25 person-hours are required to make 5 units, then it’s 5 person-hours per unit. 100 units would take 500 person-hours, so it could be 1 person working 500 hours, 2 people working 250 hours, or 100 people working 5 hours, etc. There’s an easy trick* to this.
