What is the power output of the human heart?
The mechanical power of the human heart is ~1.3 watts. It takes a much higher rate of energy turnover (~13 watts) to provide this mechanical power, since the mechanical efficiency of the heart is very low (less than 10%).
What is the advantage for scientists of using nonscientists to collect data?
Non-scientists provide additional sources of data that scientists can use.
When does the combination of lengths form a triangle?
Provide that no one length is greater than the sum of the other two lengths.
What advantage does the metric sisten provide over English units of measure?
Mainly that it is an international standard. Also, calculations are easier in the metric system, because of the multiples based on powers of 10.
What is the definition of slide rules?
A slide rule is a simple mechanical analog calculator consisting of logarithmically graduated scales, one of which can be moved across the other so as to provide a method of multiplication or division by combining lengths on the scales.
What two things provide a mechanical advantage greater than one?
lever, gear train
Does a fixed pulley provide mechanical advantage?
yes
Explain why pulleys are in the lever family?
They provide mechanical advantage.
Can a pulley system provide both a directional advantage and mechanical advantage at the same time?
yes
Why does a fixed pulley provide only a mechanical advantage of 1?
Because it has a low input force
How is the mechanical advantage of a movable pulley determined?
The method to calculate mechanical advantage is easy to remember and is necessary when rigging the assembly to accomplish the job. The mechanical advantage of a rigging that will require upward pull can be determined by counting the number of rope lengths running between engaged pulleys and those doing the work. Likewise, if the assembly will require downward pull, count the ropes and subtract one to get the mechanical advantage number. The subtraction is necessary because with the fixed pulley, the downward pull equals the load on the other length of rope so the last "pull" rope does not provide any mechanical advantage.
What is a block and tackle used for?
Block and tackle refers to a rope threaded through a series of pulleys to provide mechanical advantage, and it is used to lift heavy objects,
What kind of simple machine is nut and bolt?
They are types of screws which are actually inclined planes that curve around the outside of a rod and the interior of a cylinder. Instead of anchoring into a surface, a bolt passes through a hole and is locked in place by the nut. At its most basic, it is an inclined plane. That inclined plane formed by the threads of the bolt is wrapped around an axle and the nut provides a mechanical advantage by being a lever (The force arm is the nut's radius). The lever can be extended (a wrench) to provide greater mechanical advantage.
Which is not a way that machines provide a mechanical advantage?
If you want me to pick the correct answer from a list of multiple choices for you, I'd appreciate it if you could give me a peek at the list for a few seconds.
What are wrenches?
A wrench is a tool used to provide grip and mechanical advantage in applying torque to turn objects-usually rotary fasteners, such as nuts and bolts-or keep them from turning.
