Solution Key
Problem 1. Suppose that you sell short 500 shares of Intel, currently selling for $40 per share,
and you give your broker $15,000 to establish your margin account. Assume Intel pays no
dividends.
a) If you earn no interest on the funds in your margin account, what will be your rate of
return after one year if Intel stock is selling at (i) $44; (ii) $40; (iii) $36?
The gain or loss on the short position is 500 P . Invested funds are $15,000.
Therefore, your...

Studies on Stress Concentration Using Experimental and Numerical Methods
ABSTRACT
This paper presents the experimental and numerical studies that had been conducted to investigate the stress concentration around a circular cutout in an isotropic material. Test specimens with circular holes were loaded in tension and bending. The tension test specimen was loaded in an Instron test machine.
By mounting a set of strain gages orthogonal to the applied...
