Abox of tools weighing 20 lb is to be lifted (occasionally—maybe twice per day) from the floor to a cart that is 46 in. high. (no control is required at the destination.) the handle of the box is 10 in. high (i. e., the handle is located 10 in. from the floor). due to the width of the box, the worker must reach 24 in. in front of his or her ankles to grasp the handle, but does not need to twist.

(a) how would you rate the coupling type (good/fair/poor)? justify your answer.
(b) fill in a niosh lifting table and compute an rwl.
(c) what is the lifting index?
(d) how would the preceding analysis change if the lifting was done with one hand?

tube or goog with be a great resource to with that question

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it

hope this
