Homework Statement
Four blocks are on a horizontal surface.
<---F2---B---Tx---A---Tz---D----Ty--C---F1-->
The blocks are connected by thin strings with tensions Tx, Ty, Tz. The masses of the blocks are A=41.0 kg, B=21.0 kg, C=29.0 kg, D=39.0 kg. Two forces, F1=47.0N and F2=71.0N act on the masses as shown. Assume that the friction between the masses and the surface is negligible and calculate the tension Tz.
Homework Equations
F=ma
The Attempt at a Solution
I calculated the total mass =130 kg
Total force 71-47= 24 N
Then the acceleration F/m=0.1846 m/s^2
Next I calculated the Tension in Tz by :
Tz -F1 = 130 * 0.1846
I got 70.9 N
I'm not sure if that's correct??
