Resistors 2 and 5 form a series circuit on the right side; their combined resistance is 14. This is parallel to Resistor 3; their combined resistance is 1/R = 1/7 + 1/14 --> R = 4.66667. The three resistors now in series are 1, 4, and combined resistors of 2, 3, and 5. The sum of the resistance...
Here's the picture.
I did try considering the circuit as a parallel circuit R1, R3, and R4 together with total resistance 21 and R2 and R5 together with total resistance 14 but that didn't work

A block of mass MB = 0.7 kg hangs from a string wrapped around a hoop that can rotate around its center. The hoop has a mass of MH = 1.3 kg and a radius of R = 0.4 m. The block descends under the influence of gravity. What is the magnitude of the acceleration of the mass in...
The torque from 2.04 meters on the left side and 2.04 meters on the right side would cancel out. Then, we are left with 0.42 meters on the right side. 0.42 meters*9.8m/s/s*mass of the beam, since T = Fr. The center of mass of the beam would be at 2.25 meters.
Homework Statement
Determine the mass of a 4.5 meter beam, if it is balanced on a fulcrum 2.04 meters from the left end. A 886 N man stands on the very left end, and a 393 N girl stands on the right end. [/B]Homework Equations
