Solution to Problem 557 | Unsymmetrical Beams

Problem 557
A cast-iron beam 10 m long and supported as shown in Fig. P-557 carries a uniformly distributed load of intensity wo (including its own weight). The allowable stresses are fbt ≤ 20 MPa and fbc ≤ 80 MPa. Determine the maximum safe value of wo if x = 1.0 m.
 

Solution to Problem 556 | Unsymmetrical Beams

Problem 556
A T beam supports the three concentrated loads shown in Fig. P-556. Prove that the NA is 3.5 in. above the bottom and that INA = 97.0 in4. Then use these values to determine the maximum value of P so that fbt ≤ 4 ksi and fbc ≤ 10 ksi.
