Propane (c3hs) is burned with air. analysis of the products of combustion shows that, the number of moles of : co2 is 8.6, co is 0.6, o2 is 7.2, h2o is 12.27, n2 is 83.6. determine the percent of theoretical air used in the combustion process

Ifa component is made of two or more materials with different modulus of elasticity (e), it is called a composite member and we calculate the factor·n". mention the formula for calculating n". also, ifn> 1, explain what will happen to the 1. transformed.gi) ifn 1, what will happen to the material when transformed material when
