a reinforced T-beam is having a flange size 90cm×12cm and web size 30 cm×25 cm . if there are 6 bars of diameter 2cm, in tensile zone, find the moment of resistance of the section . if the MR has to be increased to 1.5 times the original MR . Calculate the additional reinforcement needed both in tensile as well as in compressive zone without changing the section. Assume both side cover as 5cm , c=52.5kg/cm², t= 1250kg/cm², m=20.

A metal bar of length 30 cm, is initially at 25 oC. Then through an electrical wire heat is generated at a rate of 0.5 cal/cm3s. The left end (x = 0 cm ) is contacted with a medium at 10 oC. At the right end there is a heat loss due to the air convection at a flux of 0.6 cal/cm2s. The physical properties are, k = 2 cal/cm oC s, r = 8 g/cm3, Cp = 0.2 cal/g...

Usually, the sample size is small (n<30), we would use the t-distribution value. However, if we know the population standard deviation, we still use the z-distribution value even though the sample size is small. Describe what the reason that we use z-distribution if we know the population standard deviation.
