AI Thread Summary
To determine the tension in the right cable supporting a 35kg, 5m horizontal steel beam with one cable at the left end and another 1m from the right end, moments should be taken about the point where the left cable is attached. The calculation involves balancing the moments created by the beam's weight and the tension in the right cable. The user initially struggled with the concept of offset wires but found clarity by focusing on moment calculations. The solution was ultimately achieved with this approach. Understanding the mechanics of tension in offset wire systems is crucial for accurate calculations.

Homework Statement


a uniform horizontal steel beam of mass 35kg and length of 5m is supported by two vertical cables. the first attached at the left end and the second 1m from the opposite end. find the tension in the cable on the right.


Homework Equations


n=mgsin0



The Attempt at a Solution


I have no idea how to do this with offset wires. if they were both on the end it would be easier.
 
Physics news on Phys.org
You can start by taking moments about the end where there is one of the cables attached.
 
I solved it. Thanks!
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
