Specify suitable machine screws to be installed in a pattern of four, equally spaced around a flange, if the clamping force between the flange and the mating structure is to be 26.7kN. Recommend a suitable tightening torque for each screw if each of them is to be stressed to 75% of its proof strength

Five identical positive charges +49.8 nC are placed equally spaced around a circle of radius 14.8 cm in the xy-plane (i.e. z = 0.0 cm) centred at the origin. (answer to 1 decimal place.) (a) What is the magnitude of the resultant field at the centre of the circle? (b) An additional charge +49.8 nC is placed at coordinates (-6.4, 8.4, 0.8) cm. What is the magnitude of the resultant field at the centre of the circle now?

Two parts of a machine are held together by eight equally-spaced M6x1.0 grade 5.8 bolts that are unifomly tightened to provide a total inital clamping force of 44 kN. Each bolt has a proof stress of 380 MPa, and a threaded area of 20.1 mm^2. The elasticities are such that the member stiffness is four times as high as the member stiffness. b) You have determined that assembly procedure can reliably set the initial clamping force to within plus or...

A machine costing $214,800 with a four-year life and an estimated $20,000 salvage value is installed in Luther Company’s factory on January 1. The factory manager estimates the machine will produce 487,000 units of product during its life. It actually produces the following units: 121,800 in 1st year, 122,600 in 2nd year, 121,500 in 3rd year, 131,100 in 4th year. The total number of units produced by the end of year 4 exceeds the original estimate—this difference was not predicted....
