1. ### Find hinge force

Can you please clarify whether the rod is in equilibrium in its horizontal position or is it undergoing a circular motion.
2. ### Particle in shm

Thanks a lot. Can you please guide me to a rigorous proof of the concept of superposition? The result doesn't seem readily apparent to me. Also that is the significance of the system being linear?
3. ### Particle in shm

(d2x1)/dt2=-ω12x1 (d2x2)/dt2=-ω22x2 Isn't the property of addition of the SHM's based on the addition of forces? If ω is same we can directly add the displacements.(taking -ω2 common from the two equations) But how will i prove that the addition of SHM's in case of different ωs will result in...
4. ### Particle in shm

Homework Statement A particle is subjected to two simple harmonic motions given by x1=2[sin(100πt)] x2=2[sin(120πt+{π/3})] where x is in centimetre and time is in seconds. Find the displacement of the particle at t=1/80 Homework Equations The Attempt at a Solution The...
5. ### Free Fall Question

no on the contrary you should try it by taking time as a variable.
6. ### Rigid object in equilibrium?

try to write both 1)∑F=0 2)∑τ=0 for your system
7. ### Rigid object in equilibrium?

mmm no. what do you know about torques in static equilibrium ?
8. ### Rigid object in equilibrium?

what does the fact that the body is in static equilibrium indicate to you?
9. ### Hybridization Question

The carbon you referred to has 2 double bonds,1 on either side. To make 2 double bonds carbon requires 2 p orbitals... This is similar to the case of the triple bond..
10. ### Summing a series

Homework Statement Find the nth term and sum to n terms of the series 12,23,60,169,494.. Homework Equations The Attempt at a Solution well each term is the triple of the previous term minus some constant. 23=10*3-7 60=23*3-9 .. .. This way i am able to write the nth term as...
11. ### Object undergoing acceleration

what do you know about the initial directions of the velocity and acceleration?
12. ### Stopping a car before collision

Homework Statement A person driving a car suddenly sees a wall .At that instant velocity of the car is v. Coefficient of static and kinetic friction is μ. The mass of the car is M. To avoid the driver should ....(acc. due to gravity=g) a)apply breaks b)turn (the car shouldn't slip while...
13. ### Simple FBD problem

I wasnt having any actual problem in solving questions it was just that i wanted to check whether or not i could derive relations by using different x-y directions, but the new general equations turned out to be useless.
14. ### Simple FBD problem

from here i have got the relations 1)N=M.g.cosθ+M.a.sinθ 2) a.cosθ=g.sinθ Edit:i have forgotten to consider the normal force from underneath , i'm going to re-write the equations Edit: nevermind these equations are totally useless
15. ### Simple FBD problem

I have taken g to be the acceleration downwards due to gravity
