Determine the shape factor f for a hollow circular section having inner radius r1 and outer radius r2 (fig 1). Determine also the approximate shape factor for the case of thin section (r1 ~ r2 = r and t << r). Thats all. No other info required.   [Ans. a) f = 16r2(r23 – r13)/3π(r24 – r14); b) f = 4/π]
