Ahollow steel shaft is to transmit 4200n-mof torque and is to be sized so that the torsional stress does not exceed 120mpa . if the inside diameter is 70 per sent of the out side diameter what size shaft should be used .use preferd size . what is stress of the inside of the shaft when full torque is applied

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

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
