a) Loads move along the top beams of the frame shown below. Draw the influence lines for: (i) the moment immediately right of joint (B). (ii) the shear immediately right of joint (B). (iii) the horizontal reaction at support(E). For each influence line, calculate and indicate the magnitude of the ordinate with the maximum absolute value. b) A vehicle, which is idealized as the three point loads shown, moves across beams at the bottom chord level of the truss shown. The shape of the influence line for force in member
L_(1)-U_(2)is also shown below the truss. Calculate the ordinates of the influence line and calculate the maximum (i) compression force and (ii) maximum tension force caused by the vehicle as it crosses the structure. Note: The diagonal members are not connected to vertical members where they cross. Direction of Travel
