The jib crane is designed for a maximum capacity of 10 kN, and its uniform I-beam has a mass of 200 kg.
(a) Plot the magnitude Rof the force on the pin at Aas a function of xthrough its operating range of x= 0.2 m tox= 3.8 m. On the same set of axes, plot the x- and y-components of the pin reaction at A.
(b) Determine the minimum value of Rand the corresponding value ofx.
(c) For what value of Rshould the pin at Abe designed? (Use g= 10 m/s2.)
Derive the dynamic equation for RP manipulation of example 6.5 (Introduction to robotics by Craig)by using newton-euler's dyanamics.
a homogenous cylinder begins to roll without slipping down a plane that is inclined at an angle theta. the moment of
a piston cylinder device contains 0.3kg of r134-a initially at 0 c and 400 kpa. the cylinder is then heated until the
the heat-transfer rate to the surroundings from a person at rest is about 100w. supposed the ventilation system fails
The block is a cube that is 300mm on each side. Assume the block is incredibly tall. At steady state, what is the velocity of the block?
in an archery test the acceleration of the arrow decreases linearly with distance s from its initial value of 16000
By traversing the length of each rod with a ther- mocouple, it was observed that the temperatures of the rods were equal at the positions xA = 0.15 m and xB = 0.075 m, where x is measured from the base surface. If the thermal conductivity of ro..
a heat exchanger is to cool ethylene glycol cp 2.56 kjkg degree c flowing at a rate of 3.2 kgs from 80 degree c to 40
An exact answer is not possible, but by making a reason- able guess of the number of landings per day and the number of days of service a rough estimate is possible.
A hot brass plate is having its upper surface cooled by impinging jet of air at temperature of 15 [Degree Celsius] and convection heat transfer coefficient of 220 W/(m^2*K). The 10-cm thick brass plate ( p=8530kg.m^3, Cp=380J/(kg*K), k=110 W/(m*K), a..
One-half kilogram of water executes a Carnot power cycle. During the isothermal expansion, the water is heated until it is a saturated vapor from an initial state where the pressure is 1.5 MPa and the quality is 25%. The vapor then expands adiabatica..
Calculate the static thrusts of the rocket and turbojet engine described in the figure. The thrust T is the force necessary to prevent horizontal movement of the engine. Both engines exhaust a mass flow of 40 kg/s.
