Problem 906
For the 2-in. by 6-in. wooden beam shown in Fig. P-906. Determine the normal stress at A and B. Are these the points of maximum normal stress? If not, where are they located and what are their values?
 

Problem 905
A wooden beam 100 mm by 200 mm, supported as shown in Figure P-905, carries a load P. What is the largest safe value of P is the maximum stress is not to exceed 10 MPa?
 

Problem 904
To avoid interference, a link in a machine is designed so that its cross-sectional area is reduced one half at section A-B as shown in Fig. P-904. If the thickness of the link is 50 mm, compute the maximum force P that can be applied if the maximum normal stress on section A-B is limited to 80 MPa.
 

Problem 903
A cast iron link is 40 mm wide by 200 mm high by 500 mm long. The allowable stresses are 40 MPa in tension and 80 MPa in compression. Compute the largest compressive load P that can be applied to the ends of the link along a longitudinal axis that is located 150 mm above the bottom of the link.
 

Problem 902
Compare the maximum stress in bent rod 1/2 in. square, where the load P is 1/2 in. off center as shown in Figure P-902, with the maximum stress if the rod were straight and the load applied axially.
 

Problem 885
Solve for the support moments in Problem 825 if the ends are perfectly fixed instead of simply supported.
 

Problem 884
Compute the moments over the supports of the beam shown in Fig. P-856.
 

Problem 883
Compute the moments over the supports of the beam shown in Fig. P-853.
 

Problem 882
Compute the moments over the supports of the beam shown in Fig. P-849.
 

Problem 881
Compute the moments over the supports of the beam shown in Fig. P-846.
