Solution Steps

Step 1: Identify the Key Characteristics of Needle Roller Bearings

Needle roller bearings are a type of roller bearing with cylindrical rollers that are much longer than their diameter. They are known for their ability to handle heavy radial loads in a compact design.

Step 2: Evaluate Each Option
  • Self-aligning: Needle roller bearings are not typically self-aligning.
  • Ability to accommodate high speeds: While they can handle moderate speeds, this is not their primary advantage.
  • Lower costs: Cost can vary, but this is not a defining advantage.
  • Can carry heavy radial loads in minimal radial space: This is a key feature of needle roller bearings, as they are designed to handle heavy loads in a compact form.

Final Answer

\(\boxed{\text{can carry heavy radial loads in minimal radial space}}\)

CALCULUS AB SECTION II, Part B Time-45 minutes Number of problems-3 No calculator is allowed for these problems. 4. Consider the curve given by x^2+4 y^2=7+3 x y. (a) Show that dy/dx=(3 y-2 x)/(8 y-3 x). (b) Show that there is a point P with x-coordinate 3 at which the line tangent to the curve at P is horizontal. Find the y-coordinate of P. (c) Find the value of d^2 y/dx^2 at the point P found in part (b). Does the curve have a local maximum, a local minimum, or neither at the point P? Justify your answer.

And randomly sampled group of patients at a major U.S. regional hospital became part of a nutrition study on dietary habits. Part of the study consisted of a 50-question survey asking about types of foods consumed. Each question was scored on a scale from one: most unhealthy behavior, to five: most healthy behavior. The answers were summed and averaged. The population of interest is the patients at the regional hospital. A prior survey of patients had found the mean score for the population of patients to be μ=2.9. After careful review of these data, the hospital nutritionist decided that patients could benefit from nutrition education. The current survey was implemented after patients were subjected to this education, and it produced these sample statistics for the 15 patients sampled: x̄=3.3 and s=1.2. We would like to know if the education improved nutrition behavior. We test the hypotheses H0: μ=2.9 versus Hα: μ>2.9.

Which of the following is a key difference between the slave societies in the South and the societies with slaves in the North? Enslaved Black people in the North typically had less contact with their slaveholders than in the South. In the North, slavery was most often practiced in urban centers. Slavery was only legal in a few Northern colonies. African and African-descended people did not make up the majority of those enslaved in the North.
