内容簡介

理工科救星！

漫畫掌握材料力學

邁向頂尖科技大學；橫掃所有理工科系

擺平理論與實務問題，

平衡物理與化學性質。

易懂漫畫打好基礎，

貫通力學理論與實際材料！

機械設計與製造、微機電系統、機械工程、土木工程、建築設計、一般製造業……

理工科學生的夢想，從材料力學出發！

設計圖不只是空想，

材料力學就是所有具體建物的藍圖！

材料力學是機械工程學的重要領域，製作安全結構體的基礎學問。

不懂材料力學，理工科畢不了業！

製作物品該如何選擇材料，設計結構？

不同的製作方式，會造就不同的物品性能？

技術性的製造工程，其實處處是理論！

參透材料性質，追求完美「力平衡」，讓物品「耐操，好擋，拼第一」！

本書從簡單的書架製作出發，

告訴你材料力學的一切！

力是具有大小、方向的物理量？

物體處於靜止狀態，也有力在作用？

「力」有哪幾種？壓縮力、拉力、張力、剪力與扭力有何差別？

如何分析物體所承受的作用力，以及「力流」？

什麼是安全係數，安全係數越大越好嗎？

1kg物體所承受的重力記為1kgf？

1N（牛頓）是讓質量1kg的物體產生1m/s2加速度的力？

翹翹板是力矩的作用？

用相同力道按壓枕頭，不同方向的力會造成不同的變形？

物體的變形種類其實有很多？作用的力與計算方式皆不同？

如何考慮各種作用力，計算長椅板材所需的厚度？

本書以漫畫方式，讓讀者從力的基礎知識出發，探討物體的變形、應力、材料強度和力學性質以及材料力學的應用，不只解說理論，更教導各種力的計算方式，讓讀者打好基礎、精確計算，朝製造業、設計業、建築業甚至是學界，一步步邁進。理工科學生必修的材料力學盡在本書！
