Ini adalah slide powerpoint tentang bateri,anda boleh klik pada slide tersebut untuk mendapat maklumat ringkas penerangan tersebut.
Struktur Bateri
Bateri ialah pembekal arus untuk kendalian sistem elektrik kenderaan motor. Ia juga membekal arus semasa penjana tidak mengeluarkan arus yang mencukupi. Terdapat dia jenis plat iaitu plat positif dan plat negatif. Plat-plat ini diasingkan dengan pemisah bagi membentuk elemen (pada rajah di atas). Pemisah berfungsi untuk memisahkan plat-plat supaya tidak bersentuhan.Ia berliang bagi membenarkan bendalir elektrolit mengelilingi plat. Elemen dimuatkan ke dalam sarung sel kotak bateri dan ditutup dengan tudung supaya kedap disekelilingnya. Tamatan dibina melalui tudung untuk diikat dalam kumpulan plat positif dan negatif didudukan bersebelahan dan disambungkan dengan pengikat. Tiap-tiap tudung mempunyai liang yang berpalam untuk menambah air suling. Dua terminal ditonjolkan keluar melalui tudung dan ditandakan dengan punca (+) untuk pengenalan positif, sementara tamatan negatif ditandakan dengan (-).
Pengenalan Angkup Vernier

Satu alat mengukur jitu yang mempunyai ketepatan 1/1000" atau 1/100 mm. Angkup Vernier terdiri daripada dua bahagian iaitu satu bingkai berbentuk L dengan rahang boleh gerak dan satu bingkai yang mengandungi batang dengan rahang tetap (jaw). Batang mempunyai skala utama dalam inci(imperial scale) dan metrik (metric scale). Rahang boleh gerak mengelangsar di sepanjang batang. Bacaan boleh dikunci ke batang oleh satu skru pengapit (locking screw).Rahang luar ( External jaw) boleh mengukur garisan diameter bulatan, ketebalan dan panjang benda kerja. Rahang dalam (external jaw) boleh mengukur jarak, garis pusat gerek dan lubang, manakala bilah kedalaman (depth measuring blade) boleh mengukur kedalaman sesuatu lubang.
Pengenalan Mikrometer

Mikrometer ialah satu alatan yang jitu digunakan untuk mengukur. Terdapat dua jenis bacaan mikrometer iaitu dalam inci dan milimeter. Mikrometer mempunyai bingkai (frame), sarung (sleeve), pengumpar (spindle), dan andas (anvil)dan jidal (thimbel) Jarak di antara andas dan pengumpar boleh dikecilkan atau dibesarkan dengan memusing jidal. Nat pengunci (lock nut) digunakan untuk mengunci pengumpar supaya tidak bergerak. Satu gear sehala (rachet) digunakan untuk memberhentikan pengumpar dalam sentuhan sebenar.

AN ACCOUNT OF WOMEN’S PROGRESS IN ENGINEERING: A SOCIAL COGNITIVE PERSPECTIVE Christina Vogt University of Southern California and Gender Watch(ers)
ABSTRACT
Traditionally, women were not welcome in higher education, especially in male-dominated fields. Undoubtedly, women have dramatically increased their enrollments in many once male-only fields, such as law, medicine, and several of the sciences; nevertheless, engineering remains a field where women continue to be underrepresented. This has often been attributed to social barriers in engineering classrooms. However, a new turn of events has been reported: Young women entering engineering may receive higher grades and have a greater tendency to remain than men. To examine what has recently changed, the author applied Bandura’s triadic model of reciprocity between environment, self, and behavior. The measured variables included academic integration or discrimination, self-measures of academic self-confidence, engineering self-efficacy, and behaviors taken to self-regulate learning: critical thinking, effort, peer learning, and help seeking. The data revealed that women apply slightly more effort and have slightly less self-efficacy than men. Their academic confidence is nearly equal in almost all areas. Most significantly, many previous gender biases appear diminished, and those that do exist are slight. However, it is recommended that continued efforts be undertaken to attract and retain women in engineering programs.
from my dearest sis thanx a lot.

THE EFFECT OF WORLD WAR II ON WOMEN IN ENGINEERING Anne M. Barker The John D. Hromi Center for Quality and Applied Statistics, Rochester Institute of
ABSTRACT
The field of engineering has been one of the most difficult for women to enter. Even with an increase in the proportion of women in the engineering workforce from 0.3% before the 1970s to 9.5% in 1999, women are still seriously underrepresented. This article examines the history of women in engineering in the United States during World War II. Women were actively recruited as engineering aides by the federal government, which saw them as a temporary substitute for men who were in the military. Yet this crisis did not break down the barriers to and prejudices against women in engineering, nor did it give them a real opportunity to become professional engineers equal to men. After the war, calls for a return to normalcy were used to reestablish social norms, which kept women at home and reserved desirable places in the workforce, including in engineering, for men.

Utamakan Keselamatan Di Bengkel Automotif
Awaslah ketika berkerja dengan enjin yang bergerak atau enjin yang sebaik sahaja dimatikan. Akibat kelalaian mungkin kemalangan akan berlaku. Berikan perhatian yang lebih pada bahagian yang bergerak atau binaan enjin yang panas seperti kipas dan talisawat, karburetor dan salur bahan api, litar voltan tinggi sistenm penyala, radiator, Pancarongga dan ekzos, tudung bonet, atau bahan-bahan kimia yang terlibat di penyelenggaraan enjin. Utamakan keselamatan diri anda, ikuti langkah-langkah keselamatan dan amalan keselamatan yang telah disediakan pada bengkel anda.
