Ishlab chiqarishdagi baxtsiz xodisalar va baxtsiz xodisalarni tekshirish

3. Yaltirovchi chiziqlar usuli.



l = 0,5L, m, (1.8)
bunda l – devordan joylashish chizig’igacha masofa.
Chiziqli yorug’lik oqimining chiziqligi quydagiga teng:
, (1.9)
bunda K₃ – zaxira koeffitsienti;
µ – akslangan yorug’lik va uzoqlashgan chiziq tasirini inobatga oluvchi koeffitsient;
L_L = L=20 m;
E_H = 400 lk;
Σе – hisoblash natijasidagi shartli yoritilganlik yig’indisini chiziqning barcha bo’laklarini 42.84 ga teng deb olamiz.
H’=H-0,3.
Natijaviy jadval: 2.2.

2.4. Mustaqil tayyorlanish uchun savollar:
1. Yoritilganlik nima?
2. Yoritilganliknin sifat ko’rsatkichlari sanab bering.
4. Suniy yoritishni me’yorlashtirishda hisobga olinadigan omillar.
5. Ko’zni qamashtiruvchi ta’sirni cheklash talabi.
6. Chiroqning solishtirma quvvati hisoblash usulini tushuntiring.
7. Stroboskopik effect nima.


III. Hisobot tayyorlash.
Hisobot tayyorlashda qo‘yidagilarga amal qidinadi:
1. Titul varog‘i (ilova 1 ga qarang).
2. Topshiriq shaklini o‘zgartirilmagan holatda to‘ldirish (word da yozish va tahrirlash qonun qoidalariga qatiy rioya etgan holda).
3. Nazariy savollarga javob berish.
4. Amaliy topshiriqni bajarish.
5. Bajarilgan ishlar bo‘yicha xulosa chiqarish. (ilova 2 ga qarang).
6. Foydalanilgan adabiyotlar va internet xavolalari ruyhati.
7. Baholash mezoni: №1 topshiriq bali 6 bal.
