In November 1942, he was also appointed Supreme Commander Allied Expeditionary Force of the North African Theater of Operations (NATOUSA) through the new operational Headquarters Allied (Expeditionary) Force Headquarters (A(E)FHQ). The word "expeditionary" was dropped soon after his appointment for security reasons. The campaign in North Africa was designated Operation Torch and was planned underground within the Rock of Gibraltar. Eisenhower was the first non-British person to command Gibraltar in 200 years.
What was the code name of the North African campaign?
Operation Torch

Large brushes are desired for a larger brush contact area to maximize motor output, but small brushes are desired for low mass to maximize the speed at which the motor can run without the brushes excessively bouncing and sparking. (Small brushes are also desirable for lower cost.) Stiffer brush springs can also be used to make brushes of a given mass work at a higher speed, but at the cost of greater friction losses (lower efficiency) and accelerated brush and commutator wear. Therefore, DC motor brush design entails a trade-off between output power, speed, and efficiency/wear.
Whate are small brushes favorable for?
speed

According to an October 1998 report by the United States Bureau of Land Management, approximately 65% of Alaska is owned and managed by the U.S. federal government as public lands, including a multitude of national forests, national parks, and national wildlife refuges. Of these, the Bureau of Land Management manages 87 million acres (35 million hectares), or 23.8% of the state. The Arctic National Wildlife Refuge is managed by the United States Fish and Wildlife Service. It is the world's largest wildlife refuge, comprising 16 million acres (6.5 million hectares).
