Both pulleys are fixed to the shaft and as the shaft turns with constant angular velocity, the power of pulley A is transmitted to pulley B. Determine the horizontal tension T in the belt on pulley B and the x, y, z components of reaction at the journal bearing C and thrust bearing D if u = 0. The bearings are in proper alignment and exert only force reactions on the shaft. 300 mm 250 mm 150 mm 80 mm 200 mm T 50 N z y A B C D x 80 N 65 N u Prob. 583
Implied Powers McCulloch v. Maryland- an 1819 supreme court decision that established the supremacy of the national government over the state governments. Led by Chief Justice John Marshall, held that Congress has certain implied powers in addition to the powers enumerated in the Constitution. The Constitution was meant to permit Congress to use all means “necessary and proper” to fulfil its responsibilities. Set forth two constitutional principles: - Supremacy of the national government over the states. - The national government has certain implied powers that go beyond its enumerated powers. Enumerated powers – powers of the federal government that are listed explicitly in the Constitution.
