For the net moment at the tire contact point B to be zero, the moments about B due to weight of dirt and and force on handle need to be balanced.
So, equate sum of moments about B=0 and solve for value of F
Chapter 2, Problem 2/036 Multistep A man exerts a force F on the handle of the...
Chapter 2, Reserve Problem 036 At a temperature of 54°F, a 0.12 in. gap exists between the ends of the two bars shown. Bar (1) is an aluminum alloy (a = 12.4 x 10-6/°F] and bar (2) is stainless steel [a = 8.3 x 10-6/F]. The supports at A and C are rigid. Determine the lowest temperature at which the two bars contact each other. Assume L1 = 45 in., L2 = 63 in. (1) Answer: Final temperature = the...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
