Jacobs’ nuts-and-bolts mechanics guide covers what a layperson or newbie mechanic would need to get a foothold in the field.
Though little attempt is made to go into any particular depth, the book’s scattershot compilation of everything from parts to pumps will well serve anyone entering the world of mechanics for the first time. The initial chapter on basic mechanical theory addresses measures and motion, ending with the devices that control and power many of today’s machines. Chapter 2, “The Six Machines,” delves into levers, gears, screws and the concept of mechanical advantage, and in “Mechanical Components,” Jacobs goes intocams, solenoids, rollers, clutches, chains and a rudimentary description of the four-stroke gasoline engine. The next chapter, aptly named “Tools,” covers a wide range of basic hand tools, from hammers to pliers, including a few common power tools. The final chapter, “Mounting and Fastening Components,” introduces everything from bolts to bearings, with a smattering of electrical connections and a brief introduction to levers and linkages. Every chapter is rife with visuals to help identify the tools, parts, devices and concepts being presented. In most cases, the thumbnail illustrations are enough to get the author’s point across, and the photos adequately portray the subject matter. Since the book is so light on text, readers can easily go cover to cover in a very short time, grasping basic mechanical concepts without getting overly technical. However, the book suffers from a few drawbacks that could be easily remedied. In some cases, there’s a needless repetition of illustrations and photos, as when showing screw slot types. In other instances, some illustrations—such as those covering clutches, cams and levers—are simply too rudimentary to convey the author’s intention. The page layouts could be improved through the use of a professional designer: With an arbitrary mix of illustration and photography (black and white and color), there seems to be little consistency from page to page in terms of design.
An informative first book for novices that covers a wide range of basic mechanics, tools and measures.
Privately published by Strunk of Cornell in 1918 and revised by his student E. B. White in 1959, that "little book" is back again with more White updatings.
Stricter than, say, Bergen Evans or W3 ("disinterested" means impartial — period), Strunk is in the last analysis (whoops — "A bankrupt expression") a unique guide (which means "without like or equal").
This early reader is an excellent introduction to the March on Washington in 1963 and the important role in the march played by Martin Luther King Jr. Ruffin gives the book a good, dramatic start: “August 28, 1963. It is a hot summer day in Washington, D.C. More than 250,00 people are pouring into the city.” They have come to protest the treatment of African-Americans here in the US. With stirring original artwork mixed with photographs of the events (and the segregationist policies in the South, such as separate drinking fountains and entrances to public buildings), Ruffin writes of how an end to slavery didn’t mark true equality and that these rights had to be fought for—through marches and sit-ins and words, particularly those of Dr. King, and particularly on that fateful day in Washington. Within a year the Civil Rights Act of 1964 had been passed: “It does not change everything. But it is a beginning.” Lots of visual cues will help new readers through the fairly simple text, but it is the power of the story that will keep them turning the pages. (Easy reader. 6-8)
