The block A and attached rod have a combined mass of 60 kg and are confined to move along the 60° guide under the action of the 800-N applied force. The uniform horizontal rod has a mass of 20 kg and is welded to the block at B. Friction in the guide is negligible. Compute the bending moment M exerted by the weld on the rod at B
The vertical deflection in a simply supported beam follows the following equation: v = -[(w_0*x)/(360LEI)](7L^4 - 10*L^2*x^2 + 3*x^4) What is the equation for the applied load w(x)
A vertical curve of 600 ft in length is used to connect two tangents with the following locations: Tangent 1.- Point 1, Sta = 59+00, El = 1250.0' Point 2, Sta = 72+00, El = 1190.0' Tangent 2.- Point 1, Sta = 72+00, El = 1190.0' Point 2, Sta = 84+0..

Suppose that the acceleration of the train during the interval time from t=2 to t=4 s is a 2t m/s^2, and at t = 2 s its velocity is v = 180 km/hr. What is the train's velocity at t = 4 s
Air pollution in a city is caused by the following four sources: vehicle exhaust (V), industrial exhaust (I), dust (D), and pollen from plants and trees (T). On a particular day, the likelihood of air pollution caused by these sources is 4:3:2:1, ..
A centrifugal water pump has an impeller with r1 = 4", r2 = 12", f1 = 160°, f2 = 170°. The impeller is 2" wide at the inlet end and ¾" at the outlet. For a speed of 1800 rpm, neglecting losses and vane thickness
