We first analyze for drawing stress for tube drawing through conical portion of die by slab method. The shear deformation at entry and exit is treated separately below. Generally during drawing, both the mean diameter of tube and its thickness change. But variations in both of these cannot be taken simultaneously in the slab method. So in the following analysis [...]
A transient can be a unidirectional impulse of either polarity or a damped oscillatory wave with first peak occurring in either polarity. The term transients has been used in the analysis of power system variations to denote an event that is undesirable and momentary in nature. The notion of a damped oscillatory transient due to an RLC network is probably [...]
In this essay the tests which are done during water analysis are: 1. Physical Tests 2. Chemical Tests 3. Biological Tests. Essay # 1. Physical Tests: The physical tests include the following tests: (i) Temperature: The temperature of water is measured by means of ordinary thermometers. From the temperature the density, viscosity, vapour pressure and surface tension of water can [...]
