The ancient Greek understanding of physics was limited to the statics of simple machines (the balance of forces), and did not include dynamics or the concept of work. During the Renaissance the dynamics of the Mechanical Powers, as the simple machines were called, began to be studied from the standpoint of how far they could lift a load, in addition to the force they could apply, leading ...
Thermodynamic work is one of the principal kinds of process by which a thermodynamic system can interact with and transfer energy to its surroundings. This results in externally measurable macroscopic forces on the system's surroundings, which can cause mechanical work, to lift a weight, for example, [1] or cause changes in electromagnetic, [2] [3] [4] or gravitational [5] variables.
Power is the rate with respect to time at which work is done; it is the time derivative of work: =, where P is power, W is work, and t is time. We will now show that the mechanical power generated by a force F on a body moving at the velocity v can be expressed as the product: P = d W d t = F ⋅ v {\displaystyle P={\frac {dW}{dt}}=\mathbf {F ...
[7] [9] [19] Assume the container A completely encloses the object C, without an opening (this assumption is explained below), and that C has a charge of Q coulombs. The electric field of the charge C will cause the charges in the volume of the metal to separate, creating regions of induced charge on the inside and outside surfaces of the shell.
Gopal Pandey (1883–1914) was the first person to write a book in Nepali about mathematics. He wrote four editions of his book in Nepali. The third edition was also published in Hindi. He was honoured as the Royal Astrologer for successfully predicting the number of lunar eclipses in 1884. He was also responsible to make the plot of Tudikhel. [9]
The mostly used turbines are Pelton and Cross-flow types. Most of the MHP turbines are manufactured locally. The first turbine manufactured at the Balaju Yantra Shala Pvt. Ltd. (established 1960) was a 5 kW propeller turbine for the first MHP of Nepal in 1962. Kathmandu Metal Industries Pvt. Ltd., Nepal YantraShala Energy, Nepal Hydro & Electric Pvt. Ltd., Nepal Machine and Steel Structure, a
The data will be processed to calculate the potential to exploit solar radiation to meet the energy demand of the country. Energy Auditing and Conservation in order to minimize the energy waste. Energy Auditing is the tool used for the purpose. Diversification of Solar Technology. The activity covers activities such as proliferation of ...
Mental calculation consists of arithmetical calculations using only the human brain, with no help from any supplies (such as pencil and paper) or devices such as a calculator. People may use mental calculation when computing tools are not available, when it is faster than other means of calculation (such as conventional educational institution ...
