A 10-kg rod is pin connected to its supports and has an angular velocity 2 rad/s (clockwise) when it is in the horizontal position. the length of the rod is 6 m. Determine (a) its angular acceleration and (b) the horizontal reaction force at A.
(a) angular acceleration (rad/s^2)
(b) Ax (newton)
how many students have heights (a) greater than 72 inches, (b) less than or equal to 64 inches, (c) between 65 and 71 inches inclusive, (d) equal to 68 inches. Assume the measurements to be recorded to the nearest inch.
A fish hanging from the bottom of the spring oscillates vertically at a frequency of 2.00 Hz. Ignoring the mass of the spring, what is the mass of the fish?
Water is flowing in a 6-cm diameter pipe at 20 m/s at 10?C. If the pipe enlarges to a diameter of 12-cm, calculate the reduced velocity. Also, calculate the mass flux rate and the flow rate.
Determine if the bridge would fail under a given load. The truck has two axles and the graph should should begin with 1 axle 7 ft into bridge with the other just reaching the bridge.
A particle travels along a straight line with a constant acceleration. When s=4ft, v=3ft/s and when s=10ft, v=8ft/s. Determine the velocity as a function of position.
A company near City X want's to know how much benzene they can release into River Y. City Z is 85.5 miles downstream from City X. City Z doesn't want to have Benzene levels higher than 0.0000015 g/L.
What would be the absolute pressure, P in kPa, of carbon dioxiode at 20 degrees celcious if the specific weight of carbon dioxide at 20 degrees celcious is 18 N/m^3 and the gas constant, R =1.889x10^2 J/kg*K.
A Charpy V Notch test was conducted for an ASTM A572 Grade 50 bridge steel. the average values of the test results at four different test temperatires were found to be 10ft.lb -(-50 F) 15 ft.lb- 0F 40 ft.lb- 40F 60 ft.lb-100 F
Important information about Mechanical engineering dynamics, A 3000 lb car rests on a horizontal street out of gas with its brakes locked.
the recommended threshhold limit value ( TLV-ACGIH) air concentration for occupational exposure to water-insoluble hexavalent chromium Cr (VI) is 0.01 mg/M^3. this concentration is based on an assumption that the individual is generally healthy an..
An open rectangular tank contains water up to about half its depth. this tank accerlerates at a=2.2m/s2 up a slope of alpha, which causes the free water surface to form an angle theta with the horizontal plane. what is angle aplha of the slope
what is the maximum weight of the crate that the system can support? What is the angle theta required for equilibrium?
