SUMMARY

The discussion focuses on calculating the required force F to develop a clockwise moment of 120 N*m using a connected bar BC in a crescent wrench setup. The extension distance is specified as 300 mm. The equation M = Fd is utilized, where the angle of force F with respect to the x-y coordinate system is determined to be 45 degrees. The initial calculation error stemmed from not incorporating the My component, which was later corrected by considering the distance from point A to point C.

PREREQUISITES
  • Understanding of static equilibrium and moments in mechanics
  • Familiarity with trigonometric functions and their applications in force resolution
  • Knowledge of coordinate systems in two-dimensional mechanics
  • Proficiency in using the equation M = Fd for moment calculations
NEXT STEPS
  • Study the principles of static equilibrium in mechanical systems
  • Learn about resolving forces into components using trigonometry
  • Explore the application of moments in engineering mechanics
  • Investigate alternative methods for calculating moments, such as graphical methods
USEFUL FOR

Students and professionals in mechanical engineering, particularly those involved in statics and dynamics, as well as anyone working with tools that require precise moment calculations.

Homework Statement


The connected bar BC is used to increase the lever arm of the crescent wrench as shown.If a clockwise moment of Ma=120 N*m is needed to tighten the nut at A and the extension d=300mm, determine the required force F in order to develop this moment.


Homework Equations



M=Fd

The Attempt at a Solution



Wrote the x length of BC by multiplying 0.3m*cos30, then took the x-y coordinate system through the AB(for x) and perpendicular to the AB(for y).Tried to find the angle that F makes with the x-y (ABCx), found it as 45, but the result is not correct.

Your method looks ok, so please post the details of your working.
 
I solved it, found the angle between my x-y then I multiplied Mx and My.When I tried to do it I wasnt adding the My.That's why my result was incorrect.I also found another method by finding the distance from A to C.Thank you for your reply.
