the 2-kg collar is released from rest at A and travels along the smooth vertical guide. determine the speed of the collar when it reaches position B.Also ,find the normal force exerted on the collar at this position.the spring has an unstrectched length of 200mm.
The 160-N weights of the arms AB and BC of the robotic manipulator act at their midpoints. Determine the sum of the moments of the three weights about A.
locate the initial and final states on a sketch of the T-v digram. determine the mass of vapor present at the initial and final state, each in kg.
The diameter of the tube is 13 cm and its length is 60 m. Determine the overall heat transfer coefficient of this heat exchanger using (a) LMTD and (b) -NTU method.
Fluid/Dam Pressure, Compare the pressure force exerted on the face of two dams that hold a fresh water of 1000 Kg/m^3 density and a salty water of 1030 Kg/m^3
The compression strength of Kevlar 49 fiber is about one-eight of its tensile stress. Estimate the smallest diameter of a rod on which 12 um diameter Kevlar fiber can be wound without causing kinks on its compression side.
SEM212 - Aim of this demonstration is to use measurements of the load required to propagate a crack (tear) in packaging tape to determine its fracture toughness.
Determine the coordinates x' and y' of the centroid C of the area shown in the figure and calculate the moments of inertia of the area shown, about ox and oy axes.
Determine the minimum distance from a 50 ft height building from which the ball can be thrown and not hit the side of the building , but it may land on the roof depending upon how long the building is.
How long wi1l it take for the mid plane temperature to achieve 50% of its maximum possible temperature reduction?
However, even when the cylinder is pressurized, the torque T is still sufficient to keep the seam closed so that no water leaks out. Determine the angle theta degrees that requires the minimum torque T to keep the seam closed. (Hint: use Mohr's ci..
Estimate the blood pressure in each branch, assuming that blood vessels behave as rigid tubes, that we have frictionless flow, and that the vessel lies in the horizontal plane. What is the force generated at the branch by the blood? You may approx..
A cooking pot whose inner diameter is 20 cm is filled with water and covered with a 4-kg lid. If the local atmospheric pressure is 101 kPa, determine the temperature at which the water starts boiling when it is heated.
