Express Yourself: Science

This page contain all my science related articel, also contain some solved question (either solved by me or solved by others). Thanks for visiting!!

in this Science Page, I will (not yet coz didnt have time) seperate the content through 'titling', besid using label.
+ For Cases/Question/Problem : I will put "Solved" in title.
+ For Popular Science/Science Info : I will put "Info" in title.

You may also post a question in comment box..! I wanna know what you think and feel about my blog..!! Thx for commenting..!!
PS : Because I am Indonesian and start blogging using Indonesia Language.. so my blog still left some Indonesia Language.. so "Baca Selengkapnya" means "Read More" Thx.

Solved : Period of Swinging Wheel by Spring in Horizontal

Berikut sebuah soal fisika tentang pembuktian: Original : Sebuah silinder dikaitkan pada sebuah pegas dengan konstanta k sedang ujung lain pegas di tahan tetap. Sistem silinder pegas ini di letakkan pada bidang datar horizontal kasar sehingga silinder bisa menggelinding tanpa slip. Jika momen inersia silinder bermassa M adalah 1/2 MR^2 dan silindernya mempunyai jari-jari R, maka besar periode pusat massa silinder adalah... Translated : A cylinder is attached to a spring with constant k, while the other end of the spring is remain fixed (e.g. :at wall). Spring cylinder system is place on rough horizontal plane so that the cylinder can roll without slipping. If the moment of inertia of the cylinder with mass M is 1/2 MR ^ 2 and the cylinder has a radius R, then the period of the center of mass of the cylinder is the ... Answer :

Solved : An Object Held by 4 Strings in Moving Car

For this post I post a solved question of Physics subject. Here the question :

An object with mass m held by two horizontal strings and two vertical strings inside a stationary vehicle. If the vehicle start to accelerate by a, but the object inside still stay stationary toward the vehicle(object's position didn't change). Then, the distance did the car traveled for t time is...(answer in term of T1, T2, T3, T4, g, and t)
