Solve the following problem using Mohr’s Circle (it’s the easier and better approach when parts (b) and (c) are included. The following state of strain has been measured on the surface of a thin plate:εx = +30 μ ε εy = +570 μ ε γxy = +720 μ ε Knowing that the surface of the plate is unstressed and ν= ⅓, determine:(a)The direction and magnitude of the principal strains(b)The maximum in-plane shearing strain(c)The maximum shearing strain.

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k
