Pipe 2 has been inserted snugly into Pipe I. but the holes Tor a connecting pin do not line up; there is a gap s. The user decides to apply either force P:lo Pipe I or force P-, to Pipe 2, whichever is smaller. Determine the following using the numerical properties in the box. (a) If only P{is applied, find Pt{tips} required to close gap s; if a pin is then inserted and Ptremoved, what are reaction forces RAand RBfor this load case? (b) If only P2is applied, find P2{kips) required to close gap a; if a pin is inserted and P2removed, what are reaction forces R^ and RBfor this load case? (c) What is the maximum shear stress in the pipes, for the loads in parts (a) and (b)? (d) If a temperature increase IT is to be applied to the entire structure to close gaps{instead of applying forces Ptand P2), find the AT required to close the gap. If a pin is inserted after the gaphas closed, what are reaction forces .''.', and RBfor this case? (e) Finally, if the structure (with pin inserted) then cools to the original ambient temperature, what are reaction forces Rtand P

Consider the right half of the handlebar assembly only (assume the bars are fixed at the fork at A). Segments AB and CD are prismatic with lengths L, = 2 in.andL3 = 8.5 in, and with outer diameters and thicknesses d01 = 1.25 in. 101 = 0.125 in. and d03 = O.87in.,i03 = 0.ll5in, respectively as shown. Segment BC’ of length L, = 1.2 in. however. is tapered, and outer diameter and thickness vary linearly between dimensions at B and C. Consider torsion effects only. Assume G = 4000 ksi is constant. Derive an integral expression for the angle of twist of half of the handlebar tube when it is subjected to torque T = Fd acting at the end. Evaluate ‘b1-, for the given numerical1ues.
A small lab scale has a rigid L-shaped frame ABC consisting of a horizontal arm AB (length b = 10 in.) and a vertical arm BC (length c = 7 in.) pivoted al point B. The pivot is attached to the outer frame BCD that stands on a laboratory bench. The position of the pointer al C is controlled by a spring, Jt = 5 lb/in., that is attached to a threaded rod. The pitch of the threads is p = 1/16 in. Under application of load W, 12 revolutions of the nut are required to bring the pointer back to the mark. Calculate the weight W.
A polyethylene tube (length L) has a cap that when installed compresses a spring (with under-formed length L1) by an amount ?? = (L1 = L). Ignore deformations of the cap and base.

In the design in the figure, a force of Fn=1912 N in the vertical plane and a torque of Md=916 Ncm in the clockwise direction of rotation act on a machine element with a diameter of D=200 mm on the shaft resting on the A and B bearings. If the angle of the force with the horizontal is b=49o, how many Newtons is the resultant radial force to be considered in the bearing calculation of the bearing A? 1-) The diameter of the machine element on which the force acts will not be taken into account in the calculation of the bearing forces (ie, it will be assumed that the Fn force acts on the axis of the shaft). 2-) Pi number will be taken as 3.14.

Page 428. Sample Problem 6.1.Solve this problem completely;but replace theapplied point-forceon the rightfrom 1.5 kN to 2 kN.Let the one on the left remain unchanged.At the same time, instead of computing the averageshearing stress in each joint at the provided sectionn-n, please find the average shearing stress in each jointfortheworst section of the beamwherever it is(and state/show where it is), not necessarily at the providedlocation ofsectionn-n.Keep in mind that this change will result in many other changes across the board.Discuss all practicalissues in your findings.For example, where is the system likelyto fail in terms of the glued parts, and why?

Please show complete solution with formula and free body diagramA rectangular steel block is 4 inches long in the x direction, 3 inches long in the y direction, and 4 inches long in the z direction. The block is subjected to a triaxial loading of three uniformly distributed forces as follows: 48 kips tension in the x direction, 60 kips compression in the y direction, and 54 kips tension in the z direction. If ν = 0.30 and E = 29 × 106 psi, determine the single uniformly distributed load in the x direction that would produce the same deformation in the y direction as the original loading.
Q2. A specially designed wrench is used to twist a circular shaft by means of a square key that fits into slots (or keyways) in the shaft and wrench, as shown in the figure on the next page. The shaft has diameter d, the key has a square cross section of dimensions b x b, and the length of the key is c. The key fits half into the wrench and half into the shaft (i.e., the keyways have a depth equal to b/2). Derive a formula for the average shear stress Twg in the key when a load P is applied at distance L from the center of the shaft. Draw the free body diagram.
