The tubular casing of a solid rocket booster SRB for the space shuttle has a mean radius of 7176 and a wall thickness of 0479 The maximum working pressure it has to contain is 6303 MN m2 What

The tubular casing of a solid rocket booster (SRB) for the space shuttle has a mean radius of 71.76" and a wall thickness of 0.479". The maximum working pressure it has to contain is 6.303 MN m2. What is the hoop stress at this pressure? The casing is made from D6AC steel with a yield strength of 1244 MN m2. What is the safety factor S for the casing?

 

2.The length and radius of the SRB casing are fixed by the design. Obtain an expression analogous to Equation (12.14) for the mass of the SRB casing. What is the value of (ρ/σy) for the steel?
