Learning Goal: To use Mohr's circle to determine the principal stresses, the maximum in-plane shear stress, and the average normal stress in an element. The state of plane stress on an element is shown below. Let oz= 30.0 MPa, O, = -100.0 MPa, and Try = 50.0 MPa 100 MPa 50.0 MPa 30.0 MPa Part A - Construction of Mohr's circle for the state of stress For the element shown, construct Mohr's circle for the state of stress shown associated with the x plane. First, select the center of Mohr's circle (point C) and select the point that represents the state of plane stress shown (point A). Given these two points, determine the length of the line connecting these two points, which represents the radius R of the Mohr's circle.

i) Design an appropriate shaft for the application. Use n = 1.5. (Assume the value converges, no further iterations are needed. State all assumptions and decisions in the design. ii. An intern at company ABC was given a task related to procurement. He needs to design appropriate bearings at locations C and D as well as the flat belt drive. He proposed the followings:A. use 03 series 30 mm cylindrical roller bearing at location C, having a desired life of 50 kh at a reliability of 0.98, and an application factor of 1.5B. the total length of polyamide A-3 flat belt with a belt width of 25 mm is 3mIs his proposal appropriate? Justify.

The data given is: P,-2 P, (both horizontal), Q, 2 Q₂ (both vertical), radius of pulley C-220 mm, radius of pulley D 160 mm, allowable shear stress - 45 MPa. [Ans. 100 mm]

Learning Goal: To become familiar with and apply the concepts of maximum sustainable torque and power to solid and hollow circular shafts. A solid circular shaft and a tubular shaft, both with the same outer radius of c=co = 13.0 mm, are being considered for a particular design. The tubular shaft has an inner radius of ci = 8.00 mm. The shafts are to be powered by a motor operating at a frequency of f = 3.00 Hz and are to handle an attached load. Assume the cross-sections are uniform throughout the lengths of the shafts and that the materials have allowable shear stress of τallow = 96.0 MPa.   PART A: Determine the maximum sustainable torque that the solid shaft can handle.   PART B: Determine the maximum sustainable torque that the tubular shaft can handle.   PART C: Determine the maximum sustainable power that the solid circular shaft can handle without failing.   PART D: Determine the maximum sustainable power that the tubular circular shaft can handle without failing.

Required information A 24-mm-diameter uniform steel shaft is 600 mm long between bearings. Take the value of acceleration due to gravity g to be 9.81 m/s², the value of y for carbon steel to be 76.5 × 103 N-m-3, and the value of Eto be 207 × 10⁹ N/m². NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. What is the critical speed of a half-size model of the original shaft? The critical speed of a half-size model of the original shaft is rad/s.

1) Prof. K. climbed a wall and is now stuck and hungry. One of her ME 242 students saw this opportunity to test one of their pulley mechanisms to lift some pizza boxes for Prof. K. If the student is pulling the free end with a velocity of 2.75 ft/s. a) What is the mechanical advantage between the student and the pizza boxes? Hint: The link between pulleys 1 and 4 is rigid (meaning that they must move together. This is the key to solving this problem! b) What is the velocity of the pizza boxes? Be sure to indicate which direction it is moving. [Ans. to check: 1.375 ft/s] PizzA 49°F Sunny O 4x 99+ P Type here to search End PgUp PgDn PrtScn Home
