determined buckling prone areas . although the specific details of the reinforcing structures 310 will also be explained in greater detail as this disclosure progresses , suffice to say for now the use of the reinforcing structures 310 of the present invention also allows for the use of thinner side plates 300 on the stick 107 while preventing buckling of the side plates 300 at pre - determined buckling prone areas when loads placed on the stick 107 reach or exceed a given amount . with reference to the discussion accompanying fig6 below , it should be appreciated by those of ordinary skill in such art , that the number of reinforcing structures 221 , 310 to be used is a matter of design selection and need not constitute any more than is necessary to achieve the needed performance , and by limiting the number of reinforcing structures 221 , 310 used the weight of the boom 106 and the stick 107 may be minimized . with reference to the cross - sectional shown in fig4 the location and configuration of the reinforcing structures 221 , 310 will now be discussed . for purposes of brevity the following discussion will be limited to the reinforcing structure 221 for the boom 106 , however it is to be understood that the disclosure herein is equally applicable to the reinforcing structures 310 used for the stick 107 . as shown , at least one reinforcing structure 221 is attached to an inner surfaces 400 of the side plates 200 by a suitable attachment method preferably a laser welding method . as should be appreciated by those of ordinary skill in such art , it has been found that the use of laser welding to attach the reinforcing structure 221 to the side plates 200 reduces the heat effected zone surrounding the weld area , thereby allowing for thinner side plates 200 then would otherwise be required for different welding - type attachment methods . it is to be understood that the attachment location of each reinforcing structure 221 is exemplary only and it is contemplated that other attachment locations for the reinforcing structures 221 may be had such as , for example , the outer surface 401 of each of the side plates 200 . as shown , each reinforcing structure 221 comprises a substantially straight member having a base portion 404 and a rib portion 405 extending from the base portion 404 . the reinforcing structure 221 may comprise a metallic or other rigid material and has a length which is user - selected based on the failure analysis performed on at least one of the members 105 and to be discussed with reference to fig6 . furthermore , it is also contemplated that other geometry &# 39 ; s for the reinforcing structure 221 may also be used with deviating from the spirit of the present invention such as , for example , a cylindrical or flat configuration . with reference now fig5 a partial elevational view of the stick 107 is shown . again , for the purpose of brevity , the following discussion will be in reference to the stick 107 but it is to be understood that the description provided herein applied equally as well to the boom 106 . the reinforcing structure 310 is shown in hidden detail attached to the side plate 300 in an exemplary orientation β relative to the boom longitudinal axis 500 . as should be appreciated by those of ordinary skill in such art , each reinforcing structure 310 may be attached to the side plate 300 at a user - selected orientations or angles β relative the boom &# 39 ; s longitudinal axis 500 which can vary between zero ( 0 ) degrees and ninety ( 90 ) degrees . shown in fig6 is an exemplary diagram of the results of a buckling analysis performed on , for example , the boom 106 . as shown , the area denoted 600 protruding from the side plate 200 represents the location of the side plate 200 which is prone to buckling as based on a simulated load placed on the boom 106 . although a variety of methods can be used to provide the aforementioned analysis , software programs such as , for example , nastran ( tm ) can be used in conjunction with a computing system ( not shown ) to model loading characteristics on the boom 106 and stick 107 and obtain the aforementioned information related to buckling prone areas . based on the information obtained from the aforementioned buckling analysis , the overall length of each reinforcing structure 221 , 310 as well as size of the respective base and rib portions 404 , 405 may be chosen without undue experimentation . in use and in operation , each reinforcing structure 221 , 310 may be located on the boom 106 , the stick 107 , or both so as to bolster those identified failure - prone areas 600 which may be prone to buckling when subject to loads meeting or exceeding a certain level . as should be appreciated by those of ordinary skill in such art , by locating the reinforcing structures 310 in only those areas which require the needed support , the weight of the boom 106 and stick 107 may be kept to a minimum , thereby providing for increased payloads and reduced cycle times for a any given job . modeling programs such as nastram ( tm ) which are typically used with computing systems may be used to identify potential areas of the boom 106 and stick 107 which may be subject to failure . as should be appreciated by those of ordinary skill in such art , by identifying failure prone locations of the boom 106 and stick 107 , the size and location of each reinforcing structure 221 , 310 may be optimized so as to minimize the weight of the boom 106 and stick 107 ; thereby increasing the potential payload of the work machine 100 . other aspects , objects and advantages of this invention can be obtained from a study of the drawings , the disclosure and the appended claims .
