By the end of this section, you will be able to:
  • Describe the steps taken by the United States to prepare for war
  • Describe how the war changed employment patterns in the United States
  • Discuss the contributions of civilians on the home front, especially women, to the war effort
  • Analyze how the war affected race relations in the United States

The impact of the war on the United States was nowhere near as devastating as it was in Europe and the Pacific, where the battles were waged, but it still profoundly changed everyday life for all Americans. On the positive side, the war effort finally and definitively ended the economic depression that had been plaguing the country since 1929. It also called upon Americans to unite behind the war effort and give of their money, their time, and their effort, as they sacrificed at home to assure success abroad. The upheaval caused by white men leaving for war meant that for many disenfranchised groups, such as women and African Americans, there were new opportunities in employment and wage earning. Still, fear and racism drove cracks in the nation’s unified facade.

Mobilizing a nation

Although the United States had sought to avoid armed conflict, the country was not entirely unprepared for war. Production of armaments had increased since 1939, when, as a result of Congress’s authorization of the Cash and Carry policy, contracts for weapons had begun to trickle into American factories. War production increased further following the passage of Lend Lease in 1941. However, when the United States entered the war, the majority of American factories were still engaged in civilian production, and many doubted that American businesses would be sufficiently motivated to convert their factories to wartime production.

Just a few years earlier, Roosevelt had been frustrated and impatient with business leaders when they failed to fully support the New Deal, but enlisting industrialists in the nation’s crusade was necessary if the United States was to produce enough armaments to win the war. To encourage cooperation, the government agreed to assume all costs of development and production, and also guarantee a profit on the sale of what was produced. This arrangement resulted in 233 to 350 percent increases in profits over what the same businesses had been able to achieve from 1937 to 1940. In terms of dollars earned, corporate profits rose from $6.4 billion in 1940 to nearly $11 billion in 1944. As the country switched to wartime production, the top one hundred U.S. corporations received approximately 70 percent of government contracts; big businesses prospered.

In addition to gearing up industry to fight the war, the country also needed to build an army. A peacetime draft, the first in American history, had been established in September 1940, but the initial draftees were to serve for only one year, a length of time that was later extended. Furthermore, Congress had specified that no more than 900,000 men could receive military training at any one time. By December 1941, the United States had only one division completely ready to be deployed. Military planners estimated that it might take nine million men to secure victory. A massive draft program was required to expand the nation’s military forces. Over the course of the war, approximately fifty million men registered for the draft; ten million were subsequently inducted into the service.

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
