Mechanical

The Mechanical skill allows a Sim to repair broken appliances, electronics, sinks, tubs, toilets, and showers at a faster speed which may eliminate the need for a repairman. The skill also reduces the risk of Sims electrocuting themselves when they try to repair electrical or electronic equipment. It can be increased by reading mechanical books from the bookshelves

The Sims
The Mechanical skill allows a Sim to repair broken appliances, electronics, sinks, tubs, toilets, and showers at a faster speed which may eliminate the need for a repairman. The skill also reduces the risk of electrocuting themselves when changing light bulbs, however, a maximum level Mechanical skill (10/10) does not eliminate the risk of getting electrocuted. Mechanical skill is also important in the promotion of the Sim's career, including (but not limited to), business, military, science, and law enforcement. In Makin' Magic, a Sim's Mechanical skill affects the number of charges charms they make will have, and how many MagiCoins they'll get for performing on the wooden stage in Magic Town.

To increase a Sim's Mechanical skill, have them read mechanical books from the bookshelves. In Livin' Large, a Sim can use the woodworking table and make gnomes to increase their Mechanical skill. The higher their Mechanical skill, the faster they make gnomes and the higher the price each gnomes can be sold for. In Makin' Magic, a similar table, the Kraft-a-Gargoyle table is introduced, which also increases the Mechanical skill. In Makin' Magic, Sims can also increase Mechanical skill by using the Prick-Me-Not Spinning Wheel.



The Sims 2
This skill is mainly useful for repairing things, but is also needed to advance in some careers. If Open for Business is installed, it helps in building the Robotics and Toy Making Talent badges. A Sim's mechanical skill determines the chance of getting electrocuted when attempting to repair a broken electrical or electronic object. It can be studied from a book, or learned by repairing broken items or by using the TraumaTime "Incision Precision" Surgical Training Station. In console versions, mechanical skill may be gained from the "Jimmy three fingers" rocket bench.

If the The Sims 2: FreeTime is installed, studying the mechanical skill from a book will increase a Sim's enthusiasm for the Tinkering hobby. There is also get a broken down car which builds Sims' mechanical skill while they repair it.
