Describe the stress involved in a card board box collapsing when you sit on it.

You must lean quite far forward as you rise from a chair (try it!). Explain why.

After an unfortunate accident occurred at a local warehouse, you were contracted to determine the cause. A jib crane collapsed and injured a worker. An image of this type of crane is shown in the figure.The horizontal steel beam had a mass of 88.50 kg per meter of length, and the tension in the cable was T = 12560 N. The crane was rated for a maximum load of P 500 kg. If d = 5.000 m, s = 0.558 m, x = 1.050 m, and h = 1.980 m, what was the magnitude of W1 (the load on the crane) before the collapse? The acceleration due to gravity is g = 9.810 m/s². 444.23 Wi = N Incorrect What was the magnitude of force Fp at the attachment point P? Fp = N

A television set rests on four rubber pads, each one having a height of 1.0 cm and a radius of 0.60 cm. If a 200-N horizontal force is applied to the television set, what is the shear stress on each of the pads assuming they do not slide on the floor? O A) 177 N/m2 B) 4.42x105 N/m² O C) 1.77x106 N/m2 D) 44.2 N/m2 acer Pauso Prisc Scrik F12 F11 F10 Home Ins SREATH End UGG Del KEFFECT WAVE# P Enter
