Mechanical advantage is a measure of the force amplification achieved by using a tool‚ mechanical device or machine system. Ideally‚ the device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever. Machine components designed to manage forces and movement in this way are called mechanisms. An ideal mechanism transmits power without adding to or subtracting from it. This means the ideal

long onto the deck of a ship. He exerts a 650.0 N force parallel to the ramp. What is the mechanical advantage of the ramp? What is the efficiency of the ramp? Your response should include all of your work and a free-body diagram. Answer: 650 N is mvoed through a distance of 5m. The result is 100*9.8 N is moved up thrugh a distance of 3m. Mechnical advanatage is 100*9.8 / 650 = 1.5. The maximum mechanical advanatage can be 5m / 3 m = 1.66 Efficiency = 1.5 / 1.66 = 0.90 = 90% (7 points)

mechanical ventilation is a method to mechanically assist or replace spontaneous breathing. Mechanical ventilation‚is typically used after an invasive intubation‚ a procedure wherein an endotracheal or tracheostomy tube is inserted into the airway. It is used in acute settings such as in the ICU for a short period of time during a serious illness. It may be used at home or in a nursing or rehabilitation institution if patients have chronic illnesses that require long-term ventilation assistance

Since mechanical engineering isn’t taught in high school‚ young students don’t know much about it. Can you describe mechanical engineering? Mechanical engineering is by far the most broad-based branch of engineering. Most high school students associate the field with auto mechanics‚ but that’s an enormous misconception. Mechanical engineers today are concerned with the design‚ development and manufacture of a variety of energy conversion and machine systems. Those systems include aerospace‚ automotive

: Mechanical Engineering The day to day duties of a mechanical engineer are at first repetitive‚ but over time and with advancement work varies. The average mechanical engineer works anywhere from thirty-five to fifty hours a week. If the engineer is ahead of schedule the hours may be less. Depending on which type of engineer you want be‚ you will either wear a uniform or semiformal clothing. Usually mechanical engineers work in an office or at a desk‚ their clothes are semiformal.
