Homework Statement Hi Can anyone please help with this question? A light elastic string AB has natural length l and modulus of elasticity 2mg. Another light elastic string CD has natural length l and modulus of elasticity 4mg. The strings are joined at their ends B and C and the end A...

Yes. That is my assumption. I have a feeling it may not be valid. Is tension equal to the weight at the point of rest?

Thanks a lot. It did become an albatross. But I am slowly conquering my demons.

Thanks everyone. It has become clearer.

Homework Statement Can anyone explain the above concept in a concise manner? I am proposing that banking aids motion at maximum speed on a curved surface. I am not totally sure how to include the role of side friction and centripetal force. Any further suggestions would be appreciated...

Homework Statement Hi Guys I obtained a slighty different answer. Can anyone kindly verify where I am going wrong? The question is stated thus: A simple pendulum is of length 0.5m and the bob has mass 0.25kg. Find the greatest value for the tension in the string when the pendulum is set...

Homework Statement Hi Can anyone help with this question? It will be highly appreciated. An object of mass 6kg is whirled round in a vertical circle of radius 2m with the speed of 8m/s. If the string breaks when the tension in it exceeds 360N, calculate the maximum speed of rotation and...

Thanks for a response. I am okay with the maths but unsure about the actual diagram. Any pointers? Thanks.

Homework Statement Hi I am struggling with the diagram of this question. Can anyone help? I would have loaded my diagram but unsure how to do it. This is the question: Starting with the following statement (A+B).(A+C), show how this can be implemented using NAND gates using DeMorgans law...

Thanks a million. You are amazing! I might some other. Hope it's okay to let you know. Cheers!

Thanks for your help. I mislead you about the diagram. The inductor, capacitor and resistor are all in parallel with the supply voltage at the bottom of the circuit. Does this clarify matters? I apologize for not presenting a diagram.

Yes. That's what my circuit looks like. I have done complex numbers in my maths class. Is my solution on track? Please let me know.

Thanks everyone. I take that as a yes! My sincere appreciation and gratitude.

So, my final answer is in ohms and negative. Aside from that, is my working okay? I feel its fine but its the determinant for a distinction or a merit. Thanks.

Homework Statement Hi Can a kind person please check my solution? This is the question: Demonstrate the total current in an RLC parallel circuit using the following circuit. I can't draw it but the inductive reactance is 20ohms, capacitive reactance is 5ohms and resistor of 10ohms. All are in...
