2011年9月28日 · Hi, Okay so I am struggling again with CAD, I need help on how to understand and visualize 2-D drawings to make 3-D drawings using Solid Edge Are there any websites or places where I can understand these drawings for e.g. I am making a model of a screw jack now and I have the top ,front...

2007年2月18日 · 1. A dump truck is being filled with sand. The sand falls straight downward from rest from a height of 2.00 m above the truck bed, and the mass of sand that hits the truck per second is 55.0 kg/s. The truck is parked on the platform of a weight scale by how much does the scale reading exceed...

2011年8月10日 · I then added the 0.33 volts that the ammeter was reading to this, to get 6.78 volts. Then, I applied V=IR, 6.78 V = I (1230 ohm) to get the answer 5.52 x 10-3 A. This is the correct answer, so I assume my thinking of adding the 0.33 volts the ammeter "took" to the battery voltage was correct? Thanks for your help!

2012年3月9日 · where the r turns to z. on an induction motor (lawn mower, power drill ?, furnace motor, fridge/freezer motor) when the less than designed voltage is applied to the device that is under load, the induction motor will try to = the situation by drawing more amps to make up for loss of voltage and over heat the windings.

2018年11月19日 · Homework Statement The following figure shows a circuit containing a bulb, switch and battery. Four voltmeters are connected in it to measure potential difference. Which voltmeters give non-zero readings and which ones read terminal potential difference when the switch is 1) open and 2) closed...

2013年3月4日 · In particular, drawing lines from a and b to the center of the circle, call it O, gives a triangle with two sides of length Oa= Ob= r, the radius of the circle and one side of length ab. If we call the angle Oa and Ob make, then, by the cosine law, [itex]ab^2= 2r^2- 2r^2cos(\theta)= 2r^2(1- cos(\theta))[/itex].

2020年8月21日 · I believe it says you're supposed to delete old revision clouds on a drawing when putting a new revision on the drawing. I read Y14.35 "Revision of Engineering Drawings" 2 or 3 times and I checked Y14.1 Engineering Drawing Practices, Section 4.4 "Revisions of Engineering Drawings and Associated Lists", but can't find anything that says what we ...

2025年1月24日 · In the second drawing, he's discussing the MMF, not the flux, so the core isn't really important and isn't shown. In other words, that drawing is about the H-field, not the B-field. It is common in these drawings to simplify the sketch to the salient features, for clarity, and ignore things like the assumed symmetries of current return paths ...

2015年7月10日 · The drawing is not completely correct in this case. The 0 on the right of the vernier should be aligned with the 9 mm mark on the main scale and the next vernier on the left should be slightly in front of the 8 mm mark, that is slightly to its right - …

2017年1月10日 · Homework Statement Used a solar cell and a ray box, altering the distance from the solar cell to the light source in 10cm increments. Did the usual high school experimental controls and repeats. Assuming that the voltage is proportional to the irradiance, I am meant to graph the results...
