Answer proplem 1,3 and 1.4

A pin-jointed 2-D truss is loaded with a vertical load of 10 kN as shown in figure. The crosssectional area of the horizontal member is 150 mm² and cross-section areas of the members AC and BC are 200 mm² each. Modulus of elasticity of the truss material is 200 kN/mm². The magnitude of horizontal displacement (in mm, round off to two decimal places) of joint Cis A -6m 10 KN 5 m 4.5 m

The frame supports the distributed load shown. Determine the state of stress acting at points E and D. Show the results on a differential element at this point. 4 kN/m DA -1.5m-15m+ 3 m 1 BA 20 mm 60 mm 20 mm. 5m T D 50 mm

9. A single horizontal force P of magnitude 900N is applied to end D of lever ABD shown in the figure below. Knowing that portion AB of the lever has a diameter 36mm, determine a) the normal and shearing stresses on an element located at point H and having sides parallel to the x and y axes, b) the principal planes and the principal stresses at point H. 300 mm 120 mm y B H A 540 mm 36 mm P D
