机械工程（Mechanical Engineering）是最古老、应用最广泛的学科之一，利用工程学、物理学以及材料科学原理来设计、分析、制造以及维护机械系统。. 机械工程领域要求机械工程师对于核心领域的理解，包括力学、动力学、热力学、材料科学、结构分析以及电力学 ...
electrical和mechanical是侧重点不同的两个专业。我是electrical engineering出身。Electrical分为强电，弱电和微电。强电的研究方向是发电机，电动机，电力传输之类的电能问题。弱点的研究方向是控制，模拟电路，信号处理，单片机控制等等。
2018年1月29日 · Engineering drawings come in two flavours metric and north american (mainly US only). Metric drawings are using mm as a unit, even in architecture where a mm is a slightly small unit. North american drawings are using inches as their base unit. If they would
2015年7月23日 · Kevin Krumwiede. 457 4 7. It really is as simple as iterative exploitation of physical and mathematical laws. Of course, as you get more and more accurate, it gets harder and harder to devise methods for doing so - I'd love to see an answer that addresses these challenges in the context of the current state of the art. – Air.
2020年10月6日 · Python has been the latest in a long string of languages and platforms. My experience is that Python is probably the language with the widest range of ecosystem and applications, with the possible exception of C/C++. As such there are many different ways and paradigms to program with Python. Depending on the problem domain, the "golden standard ...
2015年5月28日 · There are two different aspects to start-up torque. One is associated with the motor and the other with the system which you are trying to drive. The start-up torque of a mechanical system is the minimum torque required to get it moving from a standstill. the start-up torque of a motor is the maximum torque which it is capable of producing from ...
2021年1月20日 · 0. "Transverse" is quite clear, it is an axis that makes 90 degrees to the reference axis. So, if the reference axis is x-axis, both the y and z axes are "transverse" to the x-axis. "Lateral" has a few different meanings and usages: a) "The lateral distance...", means the horizontal distance between the referenced axis and another axis in parallel.

2016年4月7日 · That figure is about right for a low tensile bolt. See also this calculator and this table As a reality check if we approximate to a cross sectional area of 7 mm 2 and a load of 1000 N that gives a tensile stress of 140 MPa which is below yield even for low tensile steels.
