A simple log bridge in a remote area consists of 2 parallel logs with planks across them. The log has an average diameter of 300 mm. A truck moves slowly across the bridge, which spans 2.5 m. Assume that the weight of the truck is equally distributed between the 2 legs. Because the wheel base of the truck is greater than 25 m. Only 1 set of the wheels is on the bridge at a time. Thus, the wheel load on one log is equivalent to a concentrated load acting at any position along the span. In addition, the weight of 1 log and the plank it supports in equivalent to a uniform load of 65 kN/m acting on the log. 1. Determine the max permissible wheel load W based upon the allowable bending stress of of 7MPa. 2. Determine the max permissible wheel load W based upon the allowable shear stress of of 0.75MPa. 3. Determine the max permissible wheel load W based upon the allowable deflection of 6mm. E=7380 MPa
The figure shows a schematic for a hydraulic jack. Lever AC is hinged at A. The upper valve at D is closed; the lower valve at D is open. The density of hydraulic ‡uid is 833 kg/m3. Make an estimate for the force required at C to hold the system in equilibrium. You may assume the lever is approximately horizontal, and you may neglect the weight of the platform on which the car is sitting. Be sure to include the assumptions you must make in order to obtain this estimate.
