1) The vertical displacement of joint C; ACy due to the
external loading is: (? / EA mm)
2) The rotation of member AB is:
3) If member CB experienced an increase in the temperature
by 100° F. Then the horizontal
displacement of joint E; Eh (on
mm) due to the temperature change only is
given as: (Take the thermal
coefficient,a= 6.6X10-6 ).
4) If no loads act on the truss, and member AB is 3 mm
short. Then the horizontal
displacement of joint B; Bh is:
(? mm)
5) If no loads act on the truss, and member AB is 3 mm
short. Then the vertical
displacement of joint C; Ch is:
(? mm)
For the truss shown below, use the virtual work method to find the following: (Take E-250Gpa [250 X 10 kN/m²] and A-350 mm² for all members). E +ve +ve D positive deflections E-250 Gpa A-350 mm 25 KN 4m
