ENME400 Machine Design
Studio Problem 2 – Free Body Diagram and Stress Calculations
For the proposed design cart from Studio Problem 1, teams conduct stress analysis and design the
layout of shaft(s) including the locations of bearing(s), gear(s) and wheels when necessary. For
calculations, consider shaft diameter of 25 mm.
• Determine the minimum required torque on the driving shaft(s) using acceleration calculations
• Draw free body diagram of shafts
• Determine the reaction forces and torques on the shafts
• Determine the location and magnitude of the greatest tensile, compressive, and the shear
stresses in the shaft; use a two-plane analysis if needed (see example 3-9 from the textbook).
• Draw shear and bending moment diagrams for each shaft
• Document each student’s contribution to this assignment
Students will develop an appropriate understanding of stress analysis, shaft design and find reaction
forces using equili
ium equations.
Each team will submit their assignment through Canvas in PDF format.
10 points for torque and acceleration calculations
20 points for free body diagram of shafts (at least two shafts)
20 points for reaction forces and torques on the shafts
20 points for location and magnitude of maximum tensile, compressive, and the shear stresses
20 points for shear and bending moment diagrams for each shaft
5 points for student’s contribution documentation
5 points for professionalism and well-articulated submission (clear, concise, coherent, complete)

2/16 Studio Submission
During the class today, we completed the acceleration and torque calculations on wheels using
Kinematic equations and then related Newton's first law equations. As a result, we achieved
values that seemed reasonable given the slow speed of the car, around XXXXXXXXXXN-m on each
wheel, with a wheel radius of 0.05 m . Towards the end of class, we reevaluated our chosen
wheel diameter, based on the amount of space needed below the car. After some deliberation,
we believe that the wheel diameter of .1 m was realistic, there will be some clearance between
the wheel and the bottom of the cart, this should allow for the gea
ox and motor to be
approximately 0.06 m thick, leaving 0.05 m between the bottom of these and the ground. We
also establish the total number of shafts to be 5, with an input shaft into the gear box, a layshaft
inside the gea
ox, the output shaft, then two shafts to the two rear wheels to power the cart.

Ans 1:
Torque τ = Fr sin θ
Here, F = force, r = distance from where the force is applied, and θ = angle between r and F
The minimum required torque on the driving shafts = 0 since minimum torque occurs when the value of θ is zero and therefore sin θ becomes 0. And therefore minimum torque = 0
Ans 2 Free body diagram of shafts are as follows:
Ans 3: The torque required to drive a shaft is calculated with the help of following formula: 
Torque = force x distance
Here, Force = force applied to the shaft
Distance = length of the shaft
Reaction force on a shaft is calculated as:
F = (T * R) / L,
Here: F = force, T =...
