flexure

Problem 588
The distributed load shown in Fig. P-588 is supported by a wide-flange section of the given dimensions. Determine the maximum value of w_o that will not exceed a flexural stress of 10 MPa or a shearing stress of 1.0 MPa.
 

Problem 585
A simply supported beam of length L carries a uniformly distributed load of 6000 N/m and has the cross section shown in Fig. P-585. Find L to cause a maximum flexural stress of 16 MPa. What maximum shearing stress is then developed?
 

Problem 584
A wide-flange section having the dimensions shown in Fig. P-584 supports a distributed load of w_o lb/ft on a simple span of length L ft. Determine the ratio of the maximum flexural stress to the maximum shear stress.
 

Problem 583
A rectangular beam 6 in. wide by 10 in. high supports a total distributed load of W and a concentrated load of 2W applied as shown in Fig. P-583. If f_b ≤ 1500 psi and f_v ≤ 120 psi, determine the maximum value of W.
 

Problem 580
A rectangular beam of width b and height h carries a central concentrated load P on a simply supported span of length L. Express the maximum f_v in terms of maximum f_b.
