The elasticity and resistance of the materials of engineering (1883)
Burr, William H. (William Hubert), 1851-1934 · New York, J. Wiley & sons · leaf 78
4GD = a. Then fromthe known properties of such a triangle - f … Fig.3 FD = BB = BF = 2a V3. 2^ r cos CD Hence, the equation for DB is ; r sin cp — — _ ^ = o. Hence, the equation for BF is ; r cos cp -\- a =0. Hence, the equation for FD is ; r sin cp -[ ——l — o. Taking the product of these three equations, and reducing,there will result for the equation to the…
