Concept explainers

Types of loading

In mechanical terminology, the term load indicates that external force/weight, either constant or variable, acts on a mechanical member/structure. The weight of an object of a specific material is also an external load, and the external force that works on a structure comes under the categories of loading. The external load generates its effects as stress and strain in the structure.

Pls show detailed solution Example 2.2A typical industrial-scale wind turbine has a peak efficiency of about 0.44 for a wind speed of 9 m·s−1. That is, it converts about 44% of the kinetic energy of the wind approaching it into usable electrical energy. The total air flow impinging on such a turbine with a rotor diameter of 43 m is about 15,000 kg·s−1 for the given wind speed. a) How much electrical energy is produced when 1 kg of air passes through the turbine?(b) What is the power output of the turbine?(c) If there is no heat transferred to the air, and if its temperature remains unchanged, what is its change in speed upon passing through the turbine?
Pls answer asap I will give good ratings A jet of water flows from left to right and hits a splitter block, as shown in the figure. Some of the jet is diverted upwards and some of it downwards. The incoming jet has a velocity U1=U1=1.6 m/s and a cross-sectional area A1A1. The jet that is deflected upwards has a velocity U2=U2= 0.7 m/s, a cross-sectional area A2=A2= 11 cm22 and is at an angle θ2=θ2= 35oo with respect to the horizontal. The jet that is deflected downwards has a velocity U3=U3= 0.9 m/s, a cross-sectional area A3=A3=14 cm22 and is at an angle θ3=θ3= 25oo with respect to the horizontal.
