Mechanical engineering: Maximum Power Transmitted by a V-Belt Assembly

  • #1
Summary:: Hi I’m in second year mechanical engineering and I really need help with this question! Sorry about my handwriting in the attachment I’ve put in, Ive written the question out but there is an image of figure one on the file attached. Many thanks!

[Mentor Note -- Thread moved from a technical forum, so no Homework Template is shown]

A Single Vee-belt is shown in figure 1.
The mass of the belt is 0.35kg per metre and the maximum permissible stress is 1.4MPa in the belt material.
The angle of lap is 140 degrees and the total angle of groove is 30 degrees.
If the coefficient of friction between the belt and the pulley is 0.15, determine the maximum power that can be transmitted.

Welcome to the PF. :smile:

On schoolwork / homework questions, we require that you show an attempt at the solution before we can offer tutorial help. What do you think the Relevant Equations are for this problem? Why are the coefficient of friction and the max tensile stress important?
