(Q) It is desired to select a wire rope for use in an automotive tow truck application. A single line is to be used and, considering dynamic loading involved in pulling cars back onto the roadway, the typical load on the rope is estimated to be 7000 lb. It is estimated that approximately the rope experiences 20 "bends" per day under full load. If the truck is used 360 days per year, and a design life of 7 years is desired for the rope: a. What size wire rope would you specify if the rope is to be of 6x19 IPS regular lay construction? b. What minimum sheave diameter would you recommend?

Rope safety factor (Sf) in an elevator; It is a value that is directly dependent on the number of drive pulleys, deflector pulleys used, the shape of the rope bending, and the pulley channel angle. Determine the safety factor for the pulley-drum connection given below, using V-type pulleys with a channel angle of 35°. The rope diameter is 16 mm. (Include the selected table and the selection directions in the selected graphs).

A 3 x 8 member in a diaphragm resists a tension force caused by the lateral wind pressure. Lumber is Select Structural DF-L. A single line of 7/8 in. diameter bolts is used to make the connection of the member to the diaphragm. Cu = 1.0, C = 1.0, and C = 1.0. Find: a. The maximum axial tension load using ASD. b. The factored axial tension capacity using LRFD. Hint: This is a horizontal member with sheathing on top. Think carefully about orientation when computing the net area.

(13%) Problem 5: A shop sign weighing m;g hangs from one end of a uniform beam weighing mpg. A hinge attaches the other end of the beam to a wall. The beam has a length of l1. A cable is attached to the beam a distance l2 from the hinge to help support the beam. The cable makes an angle 0 with the beam as shown. e 4 Paul's o o. Auto Repair E A 13% Part (a) On the following free body diagram, draw all of the forces acting on the beam, representing the forces as vectors. Use a coordinate systen with the x-axis on the horizontal (along the length of the beam) and the y-axis vertical (perpendicular to the beam). Use "wb" for the weight of the beam, "ws" for the weight of the sign, "FT" for the force of tension, and "H" for the force on the hinge. Finally, since we don't know the angle that the force on the hinge will act based on the diagram alone, let it be acting at an angle be denoted "o" from the positive y-axis. I A 13% Part (b) Using the free body diagram from part (a), write an…

(2) A coil spring is to be used for the front suspension of a car. The spring is to have a rate of 400lb/in, an inside diameter of 4.0-in, & a free length of 14%-in, with squared & ground ends. The material is to be oil-tempered chrome-vanadium steel. Recommend the rod diameter & the number of coils for a design load of 1,500lb.

Provide schematic diagrams and photos. Explain function of the member for the selected application.Information provided: i) Boundary/end conditions: In this instance, the column is assumed to be fixed at both ends, simulating conditions where the column is integrally connected to the floor slabs above and below, a common condition in many mechanical design contexts. ii) External axial load: Assuming the column supports a floor with a uniformly distributed load, we've calculated the total axial load on the column to be 453.589 kN. iii) Properties of the column: The cylindrical column is composed of steel, a commonly used material with a known Young's modulus (E) of approximately 200 GPa. The steel has a yield stress of around 250 MPa and ultimate stress near 400 MPa. The diameter (d) of the column is 0.3048 m, providing a cross-sectional area (A) of π*(d/2)² = 0.073 m².

A local theater effects company has been contracted to provide the stage effects for the new Broadway Musical production of "Casper, the Friendly Ghosť". One of the effects involves an enormous ghost puppet, which is manipulated through wires attached to a large crosspiece. The crosspiece must support the substantial load of the puppet at the center of the main beam (Fcenter), as well as control the puppet motion with wires attached to the arms of the crosspiece, Frot. The central load problem is modeled as a simply supported beam, while the puppet control requires a large torque at the ends of the beam, which leads to a rotational deflection of the backbone, THETA (0). Since the Q9. puppeteers must manipulate the crosspiece, its weight is of significant concern. Identify the constraints for the above design case. I. Weight of the crosspiece II. Rotational deflection Torque at the ends of the beam Strength (support load) III. IV. A. I and III B. I and II C. III and IV D. II and IV

QUESTION 2 A 13-kN hydraulic press for removing and reinstalling bearings in small-to medium-sized electric motors is to consist of a commercially available cylinder mounted vertically in a C- frame, with dimensions as sketched in the Figure shown below.

A uniform Steel strut (material Modulus of Elasticity 200 GN/m2, Poisson’s Ratio 0.3) oflength 0.5m and width 100 mm is restrained as appropriate at one end and under an axialtensile load of 25 KN applied to the other end face. It has been initially designed with a thickness of 5mm. This gives a hand calculated stressvalue of 50 MN/ m2, which is a quarter of the material’s Yield Stress, of 200 MN/m2, givinga factor of safety of four. Conduct computer FEA simulations applying element types(tetrahedral, hexahedral) and a range of element sizes (2mm, 5mm & 10mm), presenting findings in a tabulated format.
