What methods can we manufacture internal gear made of metal material?
7.5.1 A metal spring is made of a certain material. Mass pieces of different magnitudes are attached to the spring to see how much it will stretch as shown below. If the elastic limit is reached at 14 cm on the meter rule, what will we see when another mass piece is added? (2
1. What are the similarity and difference between internal energy and enthalpy? 2. Can we measure the total enthalpy of a system directly? Please give your methods, a) if yes, how to measure; b) if no, what methods can be used to measure its change? Question #1: Can we open a refrigerator in our house to cool the room down? And Why? Question #2: Can we use °C unit for temperature here? Question #3: How do you increase the thermal...
The gear wheels of the reducer, whose 1st and 2nd stage module calculations are made, will be dimensioned. You can draw the schematic picture of the gearbox (not the technical drawing, but to see the stages and gear positions). According to the gear wheel dimensions, the shaft dimensioning will be done and the forces in the gears will be calculated and diagrams of shear force and bending moment will be drawn for 3 shafts separately. (We will fill in everything...
What does it mean for an object to be charged? Neutral? What arc the methods through which a neutral object can be charged? (There are two) 3. Draw a charge distribution diagram for the following process: a Negatively charged rod is brought near (without touching) a neutral metal sphere that is attached to a heavy support made of an electrically insulating material. What does it mean for an object to be discharged through grounding? Draw charge distribution for the process...
What does the concept of state mean in an Android application? What methods can we use to allow state to be maintained?
Snell's Law and Total Internal Reflection A core of material is surrounded by another material. What is the ratio of inner index to outer if the critical angle is to be 37 degrees.
if the beam is made from a
material having an allowable tensile and compressive stress of (125
MPa tensile) and (150 MPa compressive), determine the maximum
allowable internal moment M that can be applied to the beam.

The specific heat of a certain metal can be determined by measuring the temperature change that occurs when a piece of the metal is heated and then placed in an insulated container that is made of the same material and contains water. Suppose the piece of metal has a mass of 95 g and is initially at 100°C. The container has a mass of 190 g and contains 462 g of water at an initial temperature of 20.0°C. The final...
The specific heat of a certain metal can be determined by measuring the temperature change that occurs when a piece of the metal is heated and then placed in an insulated container that is made of the same material and contains water. Suppose the piece of metal has a mass of 81 g and is initially at 100°C. The container has a mass of 199 g and contains 547 g of water at an initial temperature of 20.0°C. The final...
