Consider the double-rocker mechanism in Figure P2.6.
a. What should the relationship between the links dimensions be in order for the connecting link to make a complete rotation while the arms are rocking?
b. Assume 2a = 1 cm, h = 0.5 cm, 2d = 10 cm, and that the arms have equal length 7 cm. What is the angle of arm 1 rocking?
Using exponential smoothing with a weight of 0.6 on actual values..If sales are $45,000 and $50,000 for 2010 and 2011, what would be the forecast for 2012? (First forecast is equal to the actual value of proceeding year)
Explain the effect of the following on the rate of diffusion and provide a brief explanation why each of these factors affect the rate of diffusion.
suppose an external torque t1 is applied to shaft 1 which has polar area moment of inertia j1. gear 1 is mounted on
temperature varies with altitude. the variation in the temperature can be approximated by tt0 -beta z where t0 is the
Steam produced at 70 bar and some unknown temp. A small amount of steam is bled off just before entering a turbine and goes through an adiabatic throttling valve to atmospheric pressure. The temp of the steam exiting the throttling valve is 400C.
In a sealed piston cylinder device Nitrogen gas executes a CARNOT POWER CYCLE. The source and sink temperatures are 999 K and 333 K. Minimum pressure in the cycle is 20 kPa. The minimum volume is (1/40) of the maximum volume in the cycle. The cycle w..
give a clear explaination on shear force and bending moment distributions using singularity functions?how do we use
Verify that heating the wire may be treated as a lumped-capacity process, find the steady-state temperature of the wire and find how long it takes for the temperature of the wire to reach 100°C.
Common aluminium foil for household use is nearly pure aluminium. A box of this product at a local supermarket is advertised as giving 69ft2 of material (in a roll 304 mm wide by 21.0 m long). If the foil is 0.3mil (7.62 μm) thick, calculate the num..
Calculating temperature, water evaporation, and heat in a power plant cooling situation. In a nuclear power plant the cooling tower system must be run on a closed cycle.
