Can anyone help with my question please? I am totally stuck!

Homework Statement A gear ratio is req from A/D of 1:100 and that it will be necessary to redesign D so that it has 100 teeth. Determine: a)number of teeth on c b)number of teeth on planet gears. This followed on from another question. An epicyclic gear c is the annulus and is fixed. The...

Hi, I have RA= 30 KN POINTING UP. RB= 50 KN POINTING UP 80KN pointing down, 5m long, overall length 8m

Homework Statement calculate the position from A where the maximum deflection occurs. Your answer should be accurate to 3dp. You may assume IE= 100Mn Homework Equations I'm going to go with EI d2y/dx2 = m (the 2 are meant to be squared) The Attempt at a Solution Is this equation...

0.001/0.050 = 0.02 (lateral) 1.4/800 = 1.75x10-3 (0.0075) (longitudinal) 0.02/0.0075 = 2.666 I think I finally have it, can someone confirm please? If I do then thank you to everyone who helped!

Can anyone let me know if I am heading in the right direction with my answer please?

oops! 0.01mm. -0.01mm/0.050mm = -0.02mm (lateral) 1.4mm/800 = 1.75x10-3 (0.00175) (longitudinal) lateral/longitudinal = -0.02/0.00175 = -11.428 Im not sure if this is right though as -11.428 does not tallie up with any ratio for any material for poissons ratio. What do you think?

how about: 1.4mm/800mm = 1.75x10-3 (0.00175) (longitudinal) -0.1mm/0.50mm = -2x10-3 (0.002) (lateral) lateral/longitudinal= -0.002/0.00175 = -1.1428

Homework Statement The question is: A rod of 50mm in diameter and 0.8m in length is subjected to an axial load of 150kn. If the rod entends by 1.4mm and there is a decrease in diameter of 0.01mm, determine: The value of poissons ratio? Homework Equations v=lateral strain/longitudinal...
