TRUSS PROBLEM

Determine:
a) The magnitude and direction of the reactions at 3 and 5
b) The forces in each member of the truss and determine if the truss is being subjected
to a compressive or tensile force.

answers:

a)R3 = 75 vertically upwards, R5 = 25 vertically upwards
b)F1-2 = -29, F1-3 = -87, F1-4 = -29, F2-4 = +29, F2-5 = -29, F3-4 = +43, F4-5 = +14
