Unformatted text preview:Typical front wheel suspension for an automobile
using- a coil spring is shown in the figure. If the wheel
reaction on the ground is 800 lb determine the
compression of the springThe spring has a stiffness of k =
3.5 kip/ ft and is attached to the frame of the automobile
at B. Assume the upper and lower control arms AC and
DE are pin connected to the frame at A, C, D and E. Find the horizontal and vertical components of reaction
at these pins. ' - A gate'for limiting the depth of water in a small'reservoir consists of a flat plate which seals a rectangular opening 6 ft. high and 4 ft. wide. The plate and attached frame have negligible weight and are hinged at C and coun-
' the counterweigh'o W which will limit the The pivot bearing is subjected to a parabolic
pressure distribution at its surface of contact. If the
coefficient of static friction is [1.5, determine the torque M
required to overcome friction and turn the shaft if it
supports an axial force P. Md;-
