The truss consists of three members, each made from A- 36 steel and having a cross- sectional area of 0.75 in². Determine the greatest load P that can be applied so that the roller support at B is not displaced more than 0.03 in. A C P 16 ft 16 ft B 16 ft

Each bar of the truss has a rectangular cross section, 30 mm by 60 mm. Determine the maximum vertical load P that can be applied at B if the working stresses are 100 MPa in tension and 80 MPa in compression. (A reduced stress in compression is specified to reduce the danger of buckling.) B 8m Gm 10m

Where is/are the location(s) of the maximum transverese shear stress? A simple I-beam is loaded as shown. 20 mm P KN PKN PKN Į Į -C B с D L/4 m L/4 m Midspan at point C Roller at E at the NA Section B at the top fiber Pin A at point C Midspan at point D Roller E at point D L/4 m L/4 m OE 20 mm 20 mm- 250 mm 150 mm 150 mm A
