A telephone switchboard 100 pair cable can be made up with either enameled wire or tinned wire. There will be 400 soldered connections. The cost of soldering a connection on the enameled wire will be P 1.65 on the tinned wire, it will be P 1.15. A 100- pair cable made up with enameled wire cost P 0.55 per linear foot and those made up of tinned wire cost P 0.75 per linear foot. Determine the length of cable run in feet so that the cost of each installation would be the same.
For a four pole, 16 slot armature with two coil-side/slot having lap connected progressive winding has single turn coils. The same machine is then wave wound, the emf induced in the lap wound dc machine to that of wave wound will be ________
Two wires have the same material and have the same volume. However wire 1 had cross sectional area A and wire 2 has cross sectional area 3A. If the length of wire 1 increases by ∆x on applying force F, how much force is needed to stretch wire 2 by the same amount?

কোন এক পার্কের একটি দোলনায় ঝুলতে লোহার তার ব্যবহার করা হয়েছে। কয়েকজন ছেলে-মেয়ে দোলনায় যখন দোল খাচ্ছিল তখন এক বাচ্চার অভিভাবক লক্ষ্য করেন যে, ফুলন তার 1 m থেকে বৃদ্ধি পেয়ে 1.01 m হয়েছে এবং তারটির ব্যাস হ্রাস পেয়েছে। পয়সনের অনুপাত 0.2 হলে দোলনার তারের ব্যাস কতখানি হ্রাস পায় ? (The iron wires have been used in a park to swing. When some children are swinging, the length of the wire increases from I m to 1.01 m whereas the diameter of the wire decreases which is noticed by a guardian. If Poisson's ratio is 0.2, then how much the diameter of the wire decreases?)
