find the following, assuming the truss does not deform out-of-plane: (a) the reaction forces at the supports. (b) the forces carried in each member. (c) the minimum required diameter of the tension members, assuming the members have circular cross-sections and are composed of a material that has an allowable stress of 17 ksi. (enter na for compressive members) (d) the change in length of the tension members, assuming they have circular cross-sections with the minimum diameters found in part (c), and are composed of a material that has an elastic modulus of 30000 ksi. (enter na for compressive members) (a) reactions: (if the support applies an upward or rightward force on the structure, enter a positive value, otherwise enter a negative value.)
