A hand crank generator is used to power a light bulb. The person turning the crank uses 22 Newtons of input force to turn the crank 8 revolutions in 3 seconds. Each revolution of the crank equals 0.3 meters of distance that his hand moves. A multimeter connected to the light bulb records 0.08 amps of current and 9.04 volts.
1. Calculate the input power of the hand crank generator in Watts.
2. Calculate the output power of the hand crank generator in Watts.
3. Calculate the efficiency of the hand crank generator.
Answer:
1. The input power is 17.6 Watts
2. The output power is 0.7232 Watts
3.The efficiency of the hand crank generator is approximately 4.109%
Explanation:
The given parameters are;
The force with which the crank generator is turned = 22 Newtons
The rate at which the crank is turned = 8 revolutions per 3 seconds
The distance the hand moves during each revolution = 0.3 meters
The current recorded by the multimeter = 0.08 amps
The voltage recorded by the multimeter = 9.04 volts
1. Power = The rate of doing work = Work done/(Time taken to do the work) = Force × Distance/Time
∴ The power input of the hand crank generator = 22 × 0.3 × 8/3 = 17.6 Watts
2. The power output to the bulb, P, is given by the formula for electrical power as follows;
Power = Current, I × Voltage V
∴ P = 0.08 × 9.04 = 0.7232 Watts
3. Efficiency in percentage = Output/Input × 100
Therefore, the efficiency of the hand crank generator = )Output power/(Input power)) × 100 = (0.7232/17.6) × 100 ≈ 4.109%
what is meant by engineering jobs
Answer:
Engineers work in a variety of fields to analyze, develop and evaluate large-scale, complex systems. This can mean and improve and maintaining current systems or creating brand new projects. Engineers will design and draft blueprints, visit systems in the field and manage projects.

which ctatement about traiectory is true?
why did the Underground Railroad run all the way to Canada and not simply stop in the northern free states
Answer:
Sometimes passengers stopped when they reached a free state such as Pennsylvania, New Jersey, or Ohio. After 1850, most escaping slaves traveled all the way to Canada. ... The reason was that the United States Congress passed a law in 1850 called The Fugitive Slave Act.

You get on your bike and pedal one rotation how far does the bike travel (if it stops right when the
pedal completes 1 rotation)? The diameter of the pedal sprocket is 2.5 inches. The diameter of the
wheel sprocket is 6 inches. The diameter of the back wheel is 24 inches.
Answer:
7.8 Mph
Explanation:
Rate of cycling = 1.1 rev/s
Rear wheel diameter = 26 inches
Diameter of sprocket on pedal = 6 inches
Diameter of sprocket on rear wheel = 4 inches
Circumference of rear wheel = \pi d=26\piπd=26π
Speed would be
\begin{gathered}\text{Rate of cycling}\times \frac{\text{Diameter of sprocket on pedal}}{\text{Diameter of sprocket on rear wheel}}\times{\text{Circumference of rear wheel}}\\ =1.1\times \frac{6}{4}\times 26\pi\\ =134.77432\ inches/s\end{gathered}Rate of cycling×Diameter of sprocket on rear wheelDiameter of sprocket on pedal×Circumference of rear wheel=1.1×46×26π=134.77432 inches/s
Converting to mph
1\ inch/s=\frac{1}{63360}\times 3600\ mph1 inch/s=633601×3600 mph
134.77432\ inches/s=134.77432\times \frac{1}{63360}\times 3600\ mph=7.65763\ mph134.77432 inches/s=134.77432×633601×3600 mph=7.65763 mph
The Speed of the bicycle is 7.8 mph

Type the correct answer in the box. Spell the word correctly. What is the best option possible for Gary to create an effective presentation? Gary and his team have created a new device that can help to dry clothes faster. He has to explain the mechanism of the invention to his clients through an online presentation. He would use (BLANK) tools to create accurate and uniform technical drawings for his device.
Answer:
Computer Aided Design (CAD)
Explanation:
The computer-aided design, CAD, tools are design and technical documentation technology, that makes use of an automated drafting process of drafting, rather than a manual drafting process.
Computer-aided design programs include CAD programs with 2D and/or 3D capability such as AutoCAD LT, AutoCAD, and SmartDraw which are common construction documentation drafting application with which concepts and ideas can be created and visualized
Therefore, we have;
