Homework Statement Two axels of steel are connected with gears. Both axels have the same diameter (d) and length (1000mm). Diameter of gear B is 150 mm and diameter of gear C is 450 mm. Gear D is stationary. A torque of 100 Nm is applied to gear A.Maximum allowed shearstress in the axels are...

What is the force at the end of the shaft? Is it the same as F2=300N? I sum moment at point B to try to find reaction force at A. https://dl.dropboxusercontent.com/u/11241083/New%20Document20140407191616593.pdf

Homework Statement https://dl.dropboxusercontent.com/u/11241083/tractor.png How do I calculate reaction forces at A and B? We pull with a force F2 = 300 N on the steel wire. The steel wire goes two and a half times around the axel wheel. d = 38 mm D = 200 mm a = 100 mm b = 120...

I'm sorry that is a mistake. Use g=9.81 m/s^2

My answers: BF = -1938.87 N BD = -2601.27 N My attempt at solution:https://dl.dropboxusercontent.com/u/11241083/New%20Document20140202212736894.pdf Do I only draw member CDE or do I draw EFG and CDE and then solve sum of moments about joint C equal to zero?

I'm unable to find the force in member BD. Can you please help me draw a FBD?

Do I solve sum of moments about joint C is equal to zero? https://dl.dropboxusercontent.com/u/11241083/New%20Document20140201213045922.pdf

I got the right answer for BF. How do I find BD? Do I isolate member EDC and BD and use equations of equilibrium? How do I calculate reaction force in C

At what joint do I sum moments? Do I sum x and y forces including the BD and BF forces? Can I use method of joints? I'm unable to solve this. https://dl.dropboxusercontent.com/u/11241083/New%20Document20140131230411543.pdf

Force in G is F=125 kg * 10 m/s^2=1250 N I found reaction force in A: 1250 N and reaction force in C: 0 N

Homework Statement This crane lifts a 125 kg heavey motor. What is the member forces of BF and BD? Use 10 m/s^2 as accleration of gravity. https://dl.dropboxusercontent.com/u/11241083/problemtruss.png Homework Equations F=ma Sum Fx=0 Sum Fy=0 Sum M=0 The Attempt at a...

Thanks nvn! Yes, sorry the member forces AF, CF, BC and EB are rounded off to zero as you say.

Homework Statement Calculate the member forces in the statically indeterminate truss. Member AF and BE is not connected at the intersecting point. The cross sectional area is the same for all the members. Illustration of...

Yes, that was the mistake. I got the correct answer now: \frac{17QL^4}{384EI}. Thank you nvn.
