Question 2 The wheel A and a block B are connected by a cable. The coefficient of friction of the wheel and the ground is HA = 0.4. The coefficient of friction of the block and the ground is HB = 0.3. The wheel A has mass 40 kg, and the block B has mass 30 kg, with a %3D center of gravity shown. The radius r, = 0.5m. The outer radius is 1 m. a) Determine the smallest force P (applied vertically) that will cause motion to impend. b) What type of motion is impending? (i.e. slipping/tipping at A/B)
Q.1) Draw a Free Body Diagram for each object indicated below. Include values for known forces and moments and variables for any unknown quantity. Use dashed lines to include any dimensions or angles when appropriate. Any two-force member should be modeled using a single force in the appropriate direction. (a) Draw member ABD assuming all members have negligible mass. B, C, and D are all pin connections. T 1 in. -3 in. A 50 lb 2 in. B -5 in. D 3 in. (b) Draw member ABC. Assume the mass of ABC is negligible, the mass and size of pulleys C and D are negligible and the pulleys are frictionless. A represents a pin connection.
