In the design of a supermarket, there are to be several ramps connecting different parts of the store. Customers will have to push grocery carts up the ramps. An engineer has done a survey and found that almost no one complains if the force is no more than 50 N. With a slope equal to 5°, what force must a person exert, assuming a 30 kg grocery cart (full of groceries)? Assume friction (wheels against the ground, wheel on the axle, and so on), can be accounted for by a coefficient equal to 0.10.

Problem 4: Buoyancy I Pontoon bridges use buoyant forces to support loads. This problem will ask you to consider a 10 ft section of the pontoon bridge sketched below. The bridge deck is 4 ft wide, and each 10 ft section has five 55 gallon drums on each side. Each drum has a diameter of 22 in, so the cross-sectional area of each drum is 2.64 ft², and each drum is 2.79 ft tall. Assume the bridge deck and the bracing system for the drums weigh 2300 lb per 10 ft section but occupy negligible volume. The bridge floats in water with y = 62.3 lb/ft³.

Current Attempt in Progress Plot the magnitude of the resultant R of the three forces as a function of 0 for 0 ≤ 0≤360°. After you have the plot, determine the value of 0 which makes the magnitude R of the resultant of the three loads (a) a maximum and (b) a minimum. Record the magnitude of the resultant in each case. Use values of = 64° y = 22°, F₁-59 N, F₂ = 129 N, F3 = 71 N. Answers: (a) maximum R= i N when 0= i (b) minimum R = i N when 0- i

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.
